Any one running a Flowmaster on their Disco? If so how does it sound and did it do anything for power?

By Joshua Weinstein on Thursday, May 10, 2001 - 01:21 am: Edit

I runa three chamber and I love it. the perfect blance between grunt and civility.

By Tom on Thursday, May 10, 2001 - 11:41 am: Edit

Joshua,

Do you have the part number?

By Danno on Thursday, May 10, 2001 - 07:13 pm: Edit

don't have the PN, but i know it's a 3 chamber with a 2.5" inlet/outlet
can't remember what the offsets are (center/side?)

sounds good, nothing noticable in power.

Be careful which model you get if noise levels concern you. Flowmaster makes several different "series" 3-chamber models. I had the loudest (series 40, I think - the lower the #, the louder the muffler). It sounded good, but you could hardly talk to the person next to you at 2500-3000 RPM.

I got a local exhaust shop to make me custom mandrel bent exhaust for $273 with a Flowmaster. I put on a 50 Series and love it. The guy at the shop said mine was the first Rover he had done, as there are absolutely no modified Discos around me, and how much he enjoyed doing the job on such a nice vehicle. I noticed a very slight power increase but that is probably my mind trying to make me think I got something more for the money I spent.

By Jimbo on Sunday, May 13, 2001 - 01:03 am: Edit

i use a borla. it sounds a lot better than a flow master. a flow master would make the disco sound like a j&*p or chevy which is bad. the borla makes it sound like a porsche 996 turbo which is good. there is a significant power increase and gas mileage is also increased. my only complaint is that the tip is gigantic and it decreases the departure angle. installation is direct and simple. i'd go with the borla but don't take my word for it. go to http://www.borla.com/automotive/?cartID=20010512220142207.50.49.186

By Matt Milbrandt (95discovery) on Sunday, May 13, 2001 - 06:33 pm: Edit

Contrary to popular belief, not all Flowmaster mufflers make your car sound like a top fuel dragster. If you get the 50 Series it gives your car a nice deep growl. With a custom system you can have them tuck it out of the way, cut your tip back, and it costs half as much as a Borla.

By pjkbrit on Monday, May 14, 2001 - 10:15 am: Edit

The borla is tooooooooooo noisy and creates aconstant booming resonance in the vehicle...took mine off, it drove me crazy and everyone riding in the motor kept asking me why my exhaust was blowing???!!!

By Danno on Monday, May 14, 2001 - 06:07 pm: Edit

i'll try to make a WAV file of how my disco sounds with the Flowmaster and removed resonator.

Danno

By RVR OVR (Tom) on Monday, May 14, 2001 - 10:45 pm: Edit

Danno,

You will be a hero if you do....I have heard a Borla, but not a flowmaster. For the price, I would love to get one, but would hate to regret it. Post soon!

Tom

By Chris on Monday, May 14, 2001 - 10:57 pm: Edit

Hey Tom,

I too have a flowmaster welded in with a removed resonator. I love the sound! I has a nice deep growl that is definitly not overbearing. I would highly recommend one.

BTW: No j**p sounds here!

Chris

By RVR OVR (Tom) on Monday, May 14, 2001 - 11:16 pm: Edit

Chris - a "50" series as well?

Tom

By Chris on Tuesday, May 15, 2001 - 09:09 am: Edit

Tom, I wasn't sure what type I had so I just called the guy who put it on for me. It is, in fact, a 50 series muffler (three chamber). The great part about this muffler is that you just weld it in to your existing exhaust system (rather than replacing the whole thing), so it is relatively inexpensive. The whole thing (muffler and installation) cost me roughly $130.

Chris

By Danno on Tuesday, May 15, 2001 - 10:51 am: Edit

sent a WAV to Ho to post. it's from a 3 chamber Flowmaster that i got from Summit Racing (~$60 + free shipping) and installation at Midas was $30.
it's a 2.5" center inlet / 2.5" offset outlet.

Danno
ps. the file was pretty big so i only have it at idle. send me an email and i can send a WAV with it revved to about 3k rpm's.

Definatly lowder than my Borla. Sounds like a duel exhaust chevy. A mechanic once told me that a flowmaster is about the same as a hollowed out tin can and does just about as much for your truck; mostly a sound thing (ie for show). He said that Borla has a little more science to it, but not much. He seemed to think that Borla + K&N yielded the best results, just based on his personal knowledge, no dyno tests.

By MA on Tuesday, May 15, 2001 - 05:31 pm: Edit

I have a Borla on my Disco and I think it sounds SWEET!! If you are into the sound of a 80's Porsche, then this is the exhaust for you. I am not a big fan of Flowmasters because,like Disco Infurno said, it lacks the technology found in the Borla. It is made for big Chevy trucks with red neck drivers(no offence to anyone). With the Borla, you can feel some power increase, especially in the highway. Also my gas mileage is better. It sounds really good around the 25-30mph and 45-50mph range. If you off-road a lot then you would want to replace the tip with something smaller.

By dave on Tuesday, May 15, 2001 - 06:58 pm: Edit

Don't belive for a minute that the Flowmaster is just a crappy muffler. Flowmaster knows what the hell they are doing. I have used them on cars with small and large displacement engines and have always had exceptional results. Keep in mind that Flowmaster makes many different mufflers...they don't all work or sound the same.

One things for sure, the flowmaster wont bust open at the seams as the borla is prone to doing.

By Disco Infurno on Tuesday, May 15, 2001 - 10:40 pm: Edit

Bust open at the seams? How many people have actually had this happen, and I don't want to hear the "oh my friend's did". Borla engineers their products. So does flowmaster, but I'd be very interested to see the dyno on very similar vehicles, one with Borla and one with Flowmaster. My money would be on the Borla.

By dave on Tuesday, May 15, 2001 - 10:53 pm: Edit

I have actually seen it happen on two Borla exhausts, but neither were on a Disco, they were on turbo toyota MR2's. Both were a case of polishing a weld just a little much. Borla replaced them with no problem. I think someone had posted here that it had happened to his Disco setup as well.

As far as dyno results, neither are going to produce major HP gains, not with the stock cats in place at least. I would imagine that they are pretty close.

Personally, I like the NRP exhaust, I plan on purchasing one soon. I already have the NRP Y pipe...that seemed to make a slight difference in power but helped out the gas mileage a bit. Fits great on the Disco too...perfect.

By willis on Wednesday, May 16, 2001 - 08:43 am: Edit

hmmm...Flowmaster = $60.00
NRP = $1300.00!!@@##@##
thats a tough one....

By Ray Gunn on Wednesday, May 16, 2001 - 10:21 am: Edit

Sounds like a Porsche?!!! WTF!!! If I wanted a Porsche, I would drive one. A Disco is A TRUCK! An off-road all wheel drive truck. Take that yuppie elitist shit and stick it.... If you are trying to impress someone by inferring you have a "Porsche" you need to be in the bars, trying that line on college girls. Too many people here think that more $$$ = better stuff. I have news for you: Flowmaster is a MUCH better muffler than a Borla, but for a STOCK TRUCK, neither is going to make much difference except in your pocket book. If you want performance changes, you are going to have to tweak more than your muffler.

GO POLISH YOUR DISCO AND I AM SURE THAT WE WILL SEE YOU AT THE MALL..........

By Gil Stevens (Gil) on Wednesday, May 16, 2001 - 10:41 am: Edit

I agree with you about the Porsche thing, But I didnt think it was important enought to write back about. But really, if you want a Disco to sound like a Porsche then there is an issue there. Go buy a Porsche. Those .wav files of the Flowmaster are intense. Thats exactly the sound Im looking for. Does it sound like a Chevy? sure it does, but to me it sounds like a nasty V8, be it Chevy, Ford, or Rover. I want the sound so that I have an audible indicator when im nearing my rev-limiter (manual trans). the stock Disco sounds exactly the same at 3500 rpm as it does at 5500 rpm. when you got your head out the window, in 2nd low trying to scale a rutted sloppy hill, its tough to keep an eye on the tach.

As far as "GO POLISH YOUR DISCO AND I AM SURE THAT WE WILL SEE YOU AT THE MALL.........."
what the hell is that all about?

By RVR OVR (Tom) on Wednesday, May 16, 2001 - 11:07 am: Edit

It's a darn shame when things turn elitest. Let's face it, that's an old Buick motor under the hood of your Discovery.

Tom

By MA on Wednesday, May 16, 2001 - 05:51 pm: Edit

Yes I'm still backing my statement that my Disco does sound like a Porsche. And yes I have heard Porsches(my next door neighbor has at least 3), so I'm not saying that to get college girls(whatever the hell that means?). Maybe not EVERY Porsche sounds like it, but some do. For example a new 2001 Porsche 911 Turbo sounds almost exactly like my Disco(before it heats up and booms). I agree that it doesn't make a big difference in the performance department, if you want more power, then you should replace your block with a 4.6 roverV8. I am not trying to piss people off here(like some people) I am inputting my opinion. I don't give a damn which muffler you choose. As far as more money, a Borla exhaust can be bought for less than $400 if you look around.

While we are bashing things around...what the @#!% does "GO POLISH YOUR DISCO AND I AM SURE THAT WE WILL SEE YOU AT THE MALL.........." mean? Just because I have a Borla means I don't off-road? Yeah....right????

By Blue Gill (Bluegill) on Wednesday, May 16, 2001 - 06:34 pm: Edit

What's wrong with college girls? Wish I had a sound card here at the office (they don't want us listening to porn...)

Also, Tom is right - that's an antique Buick engine...but you sure can make that V8 sound sweet. In the bucks department, my money is on Flowmaster, but if you're goin all-out, then Borla has the name recognition - but what's up with that cheesy lowrider exhaust tip? I know it's adjustable for sound, but it'll get mashed on a Disco. How will it sound then?

By bob on Wednesday, May 16, 2001 - 08:00 pm: Edit

The Borla is adjustable for sound? How do you do it?

By Blue Gill (Bluegill) on Wednesday, May 16, 2001 - 08:10 pm: Edit

local vendor told me that Borla is LOUD, but big exhaust tip lets you adjust outflow sound (tip is kind of like an adjustable resonator). This is just what I heard, leave it to someone who owns Borla to confirm or deny.

By joey g. on Wednesday, May 16, 2001 - 08:31 pm: Edit

is a flow master backed by a 1000000 mile warranty? borla is. you can drive around the world 42 times before the warranty expires!!! borla is so confident that their products will last 1000000 miles and if it doesn't, they'll fix or replace it free of charge.

By Gil Stevens (Gil) on Wednesday, May 16, 2001 - 09:18 pm: Edit

Yes the Borla is a nice system, although I agree about the tip. But we are talking about a $75.00 weld-in compared to a $400.00 "system". Ill put on a Flowmaster for the time being and when I feel like spending $400 on the exhaust system, Ill get a Borla. Right now that $400 could be much better put toward a winch. They both produce the desired effect and they both do so well. Other than sound, which is a personal preference, you really cant say anything negative about either of them.

By Kyle Van Tassel (Kyle) on Wednesday, May 16, 2001 - 09:32 pm: Edit

Something that hasnt been touched on here is construction. THe borla shit is stainless which is a very good thing for the DIsco. On the other hand , the flowmaster is nice and thick and doesnt mind the rocks so much. East coasters would probably be better suited for the borla. The West coasters have more rocks and less moisture......

Kyle

By MA on Wednesday, May 16, 2001 - 11:46 pm: Edit

Stainless steel is bad,why? Borla says it is a very well built system(T304 steel) that is built to take the abuse of the trail. I have bashed through some rocks before and had no problems. I check under there after every off-road trip that I go to, and I find no damage at all(at least not to the muffler). I agree that the tip is kind of big. I might just cut it off,cut a hole in the rear quarter panel and run a tip through there.

By Chris on Thursday, May 17, 2001 - 09:20 am: Edit

MA and others,

If you route the tip of your exhaust through your rear quarter panel like Greg Davis is that not going to discolor the side of your disco over time due to the emissions being released? I am just curious if anyone has tried this over a longer period of time and knows how the emissions affect the truck while comming out of the side panel--or if they have any affect at all. I thought about doing this last year when I cut my resonator off but in the end opted to just route it out the back a little higher than when the resonator was on.

Chris

By Blue Gill (Bluegill) on Thursday, May 17, 2001 - 12:20 pm: Edit

You have HEAT and RESIDUE (from that fire in the engine) exiting out the pipe - if you poke out the rear quarter panel far enough, you can avoid the residue part, but keep in mind the heat baking your paint. It would also look a little odd...how about a nice fat pipe goin straight out the back bumper? Twin fat pipes - one on each side - would be cool Has anyone ever thought about keeping emissions from the two banks of 4 cylinders (each side of the "V" in V8) separated all the way from the manifolds to the tailpipe? Just eliminate the point of singularity in the "Y" pipe after the cats and continue piping through 2 mufflers (one on each side) through to the rear tailpipe.

Also, if you cut the tip off the Borla, what does it do to the sound? Again, I'm goin off of what I was told - namely, the tip acts as a kind of resonator for the "system". MA - I think Kyle meant that stainless is GOOD!

By Greg Davis on Thursday, May 17, 2001 - 12:31 pm: Edit

So far I haven't had any problems with the heat from the exhaust burning my paint. Took a 3 1/2 hour road trip with no bad results. I cut the hole with at least 1/4" clearance around the pipe to keep the heat at a minimum. Plus there's alot of air circulation back there. As far as residue, yes it does get sooty back there. But so far, it has all wiped right off. Keep a good coat of wax and you shouldn't have any problems.

Now a question. Driving around without the resonator was fine. When I had the new pipe made, I had the factory pipe cut off just past the Watts linkage. This removed a curved section that originally went down to the resonator. Now I get a resonance at idle and between 1750-2000 RPM. Has anyone else encountered this? I am now considering replacing my muffler with a 50 or 70 series Flowmaster (40 series is too loud). Supposedly the 3-chamber design prevents resonance. Hooker has a similar muffler. Is this true?

By Blue Gill (Bluegill) on Thursday, May 17, 2001 - 12:34 pm: Edit

any photos?

By Paul L on Thursday, May 17, 2001 - 02:11 pm: Edit

I had a stainless system installed with a S/S Bullet muffler for $300 (installed). Better than the "overrated" (words of a custom exhaust shop owner that sells Borla) Borla, cheaper, and still impervious to rust. It's kinda loud, but I could care less if it sounds like a Ford, Chevy, Porche........it's a Land Rover, so that's what it sounds like.....

By Greg Davis on Thursday, May 17, 2001 - 10:28 pm: Edit

Bluegill, if you're asking me for pics, they're under my gallery Greg Davis. There's a new section with my rear bumper. I think the shot of my exhaust is in the lower right of that section.

By Blue Gill (Bluegill) on Friday, May 18, 2001 - 12:08 pm: Edit

Looks VERY nice! You're right about the air circulation and no-baking problem with your generous cutting. I wonder if an extra inch or two protruding outboard of the panel would alleviate the gunk problem (and help send exhaust gases further away from the truck)?

By Greg Davis on Friday, May 18, 2001 - 12:38 pm: Edit

Thanks for the compliments. I played with the idea of the pipe protruding further out, but it didn't look right. It's all a matter of whether or not you mind cleaning a little more. Either way would be fine. I actually have to tweak Mine a little more 'cause the bottom protrudes more than the top because of the curve of the body. I believe in a good balance between form following function and aesthetic.

By Ron on Friday, May 18, 2001 - 12:44 pm: Edit

Has anyone ever thought about keeping emissions
from the two banks of 4 cylinders (each side of the "V" in V8) separated all the
way from the manifolds to the tailpipe?

This is not smart. I am not sure exactly why but joining the two together is supposed to actually improve performance and reduce noise.

Ron

By Blue Gill (Bluegill) on Friday, May 18, 2001 - 05:41 pm: Edit

Yeah, there are performance issues to be concerned with (backpressure, computer controlled engine parameters, and a lot more that I have no idea about). Not to mention the undercarriage space constraints... I would think that noise would not be an issue with 2 mufflers!?

By Peter Matusov on Friday, May 18, 2001 - 06:44 pm: Edit

Ron,

the exhaust flow has pressure fluctuations that have nearly opposite phase for both banks. when you join the pipes together, they cancel each other. As a result, you have lower noise, and improved exhaust airflow.
many cars that have dual exhaust pipes have a crossover tube right after the intake manifolds (before the cats)
