At 120,000 mi. I need a new muffler. I want to go with a borla or some type of free flowing design. Main question, do I need to replace my Y pipe as well. I am getting O2 fault so I will replace the sensors, but am I sacrificing performance by not replacing entire system. I am running a chip and K & N. Cost of the Y is the main issue, if I do not need it I'd rather save the $825, that is for the SS Performance Y. Which brings up another question, if I do need to replace the Y, is the so called performance Y any better than stock? | ||

Don't bother with a high flow muffler. Land Rovers are slow. There's no sense in making it loud and slow. I want mine as quiet as it can be. | ||

You have a point there Steve, but I wonder how I will know when I need to replace the catalytic converters? | ||
| Timothy A. Green (Tree_trimmer) New Member Username: Tree_trimmer Post Number: 29 Registered: 02-2004 |
Anybody out there want to suggest when I will know it's time to change the catalytic converters on my '95 disco? | ||

Rattling and terrible performance. you will notice a lack of umph. | ||
| Timothy A. Green (Tree_trimmer) New Member Username: Tree_trimmer Post Number: 30 Registered: 02-2004 |
No rattling, but I've never noticed performance or umph out of my disco. Actually when I put the chip in it does have a little zip, but not much. | ||
| Steve Rupp (Steve_rupp) Member Username: Steve_rupp Post Number: 74 Registered: 03-2003 |
I don't think I would worry too much about the converters. They will probably out live the car depending on where you live. If they salt in the winter they may rust and fall apart, but that will happen before they get clogged. | ||

Drop in a set of headers, high flow cats, new O2 sensors, a free flow muffler and go with an electric fan. All that with the chip you already have, it should run nice....you could also go ahead and go with MSD ignition too if you want. Spend a cool grand and see how it runs, but it probably will not offset the cost for performance or fuel economy. But you will never know if you don't try things. | ||
| Timothy A. Green (Tree_trimmer) New Member Username: Tree_trimmer Post Number: 31 Registered: 02-2004 |
Joey, unless you know something I don't, a cool grand wont buy o2's, cats, and a muffler. Pleas tell me where they're at and I'll order them! Tim | ||
| Steve Rupp (Steve_rupp) Member Username: Steve_rupp Post Number: 77 Registered: 03-2003 |
If it's not broken, don't fix it. Get a LR cat back and be done with it. Spend your money on something useful. | ||
| Tbow (Tbow) Member Username: Tbow Post Number: 187 Registered: 12-2002 |
Tim You can always benefit with a free flowing exhaust system. Borla is a good bolt on system but very costly, the best value for the money is to replace the muffler with a Magnaflow freeflow muffler and remove the rear resonator. It should cost you around 150-200 dollars at your local muffler shop. It will be a good complement to your KN filter and chip. What you'll notice immediately better bottom end performance and a nice (not too loud) cound. There is no need to replace the y-pipe unless it's cracked or rusted out. If your cats are bad you'll notice a rattle or if you have emission testing, you'll fail the test, otherwise they should be fine. | ||

Thanks Steve and Tbow. That is the kind of advice I needed and was looking for. My cats are not visibly or audibly damaged, just a little concerned about what might be happening inside. The Magnaflow should save me enough so the O2's cost won't hurt so much. Thanks again. Tim | ||

Wow. And I thought my wife was a bargin hunter! Thanks a bunch. Now for the decision making. Tim | ||
| Joey (Joey4420) Senior Member Username: Joey4420 Post Number: 587 Registered: 04-2003 |
Your welcome Tim, I may not know alot about LR's Yet, or know how to off road well, but when it comes to bargin hunting and learning how to modify things...I spend much time searching before I speak.... I am looking at doing what I have posted plus the MSD ignition and rechipping. Of course all comes one at a time as I can afford and when things need replacement....what better way to upgrade then to do so when things start breaking  it is also a plus that my local mechanic (non-LR) only charges $20 a hour for any type work. (including muffler, welding, engine, etc) | ||

lets spend Tims' money! NRP exhaust system, including cats bout $1400 K&N (so what if they gum up the MAF its Tim's money not yours)Tweak timing on engine those three are good for 20 or so HP rechip and replace cam (wwwrpiv8.com) bout another 10-20 depending on options. Adjust kickdown cable change to 3.8 R&P While we are at it I think some new springs and bilsteins are in order to improve handling along with new bushes..... | ||

Don't try to build a race car out of a disco. Build it for what it is intended for. | ||

I do use my landrover for whats its designed for. Hauling stuff, towing, etc. Taking 5-people and a boat over a mountain pass at 35mph really makes these mods look good to me. ITs not about having a race car. Its maintaining the speedlimit on mtn passes. l8r Todd | ||
| Big Ed (Sandman) Member Username: Sandman Post Number: 53 Registered: 02-2004 |
Todd - nothing short of buying an F350 will make the Disco pull a boat and 5 people over a mountain pass faster than 35MPH. It's just not made to do it. SandMan Okay, maybe a bigger V8, different trans, new gearing, and stock tires would do it too. | ||

Back to Tim's original question. The Borla is a cat back system, and bolts right on. You don't need to replace the Y-pipe. Pro: It's stainless steel, and warranteed for 2 million miles. It will be the last muffler you buy, unless you mangle it off road. Cool, shiny tip at the end of the pipe. Con: It's louder than stock, but not that loud. You'll get used to it. No noticeable performance gain to speak of, and it's pricey. Cool, shiny tip at the end of the pipe. - Axel | ||

Timothy and Todd, just an update...found a better deal on the headman headers. First the ones from Summit on are only coated on the outside. 5 year rust warrenty. http://www.jet-hot.com/ sells them for $346 shipped to the door, coated inside and out with a lifetime rust warrenty. Also I talked with Summit Tech department (he is the one who suggested jet hot) and he informed me that the CTO-2540 2 1/4 Cats are $75 from summit and are list for the Land Rover OBDII. If you call they are listed under Range Rover, not Land Rover, but the do have them under Discovery...Got to love that. I talked to Flex-A-Lite Tech dept today as well and he said the LR Radiator is 27 1/8 x 15 3/8 and the 27" Flex-A-Lite electric fan should fit with minimal issues. He said maybe a little bit of work around may be invovled, but not much if any. The 27" fan is listed as 17½" x 27½" x 4" http://www.flex-a-lite.com/auto/html/27inch-electric.html And for those interested yes, I just placed my order for the headers today and they should be here it 2 weeks. I will post pics when they are installed. I will also be doing the new cats and fan at the same time. I will also let you know how the perfomance or fuel economy goes or I will post if there are no improvements at all... either way I needed new maniflods since my Right hand one is now cracked.

Man, what I've missed by being out of town for a couple of days. First off I appreciate ALL the information and responses. Secondly, I don't have any unrealistic expectations about turning my disco into a power machine. I do however need a muffler as mine is exhausting out of the middle instead of the end. And since I need to replace it I DO want to do the best thing for the poor little disco, (best for the money that is) after all I am punishing it by towing a 5,000 lb camper with it. That is why I installed the new springs and the chip. Unfortunately, I also installed the 265/75R 16s at the same time, which didn't do much for its power.(I hope you can see a trend here, these upgrades were not only for the towing improvements, got to justify these costs to the wife somehow!!!!!!!!!!!!) I know towing that kind of load with a D1 is not all that practical (and believe me I don't want to start another long discussion about the towing capacity of a disco) but I like my disco and want to keep it and eventually turn it into a credible trail rig. I can't buy a tow vehicle AND upgrade the disco too. So I do want to squeeze every PRACTICAL hp out of the little 3.9 till it bonks then upgrade to a 4.6. Hopefully that won't be for ANOTHER 120,000 miles. So I appreciate finding out that there are free flowing mufflers for less than NRP and Borla. I'd rather go a little cheaper now and down the road I may make a different decision. I don't particularly need headers now or an electric fan, but I like knowing they are available for later on. (By the way I just read electric fans are better for fording water as they can be switched off so the blades won't break and go into the radiator.) So Thanks to all, and believe me I have learned a LOT since I signed on to disco.web and regret I didn't find it sooner. I always welcome any information which may help me make better decisions about the work I do on my disco. Tim | ||

Tim Bolt on systems from companies like Borla and NRP are very good and effecient and look nice. But they are very pricy. The best value for the money is taking it to your local muffler shop and have a freeflowing muffler like a Magnaflow, Flowmaster, Dynomax... muffler installed in place of your muffler and remove the resonator and replace it with an extension pipe with a nice tip. That should cost you about 150 - 200 bucks. I've tried virtually all the popular and some not so well known mufflers available on my 96 and while you can't go wrong with any of them, I personally liked the Magnaflow the best. | ||
| michael a. kerr (Ethanrover98) Member Username: Ethanrover98 Post Number: 52 Registered: 11-2003 |
Tim, Which Magnaflow specifically do you like the best?? | ||
| Timothy A. Green (Tree_trimmer) New Member Username: Tree_trimmer Post Number: 37 Registered: 02-2004 |
Was that Tim, or Tbow, or is Tbow Tim also? I am leaning toward the flowmaster for about 60 bucks if a muffler shop can install it pretty cheap, if not the magnaflow is my second choice. Thanks Tbow. Tim | ||
| Tbow (Tbow) Member Username: Tbow Post Number: 196 Registered: 12-2002 |
The flowmasters do sound good, but fairly loud where the magnaflow's have a nice deep yet quiet sound to them. The magnaflow that fits best and has the best sound for the LR is model #11225. It's a 4x9" offset/center 2 1/4" design. Most muffler shops should be able to do it for about 125-150 dollars installed. Add another 50 bucks to remove the resonator and replace it with an extension pipe and a nice chrome tip. If you do a lot of offroading, then I might recommend a Stainless tip, but most of the time, a chrome tip is just fine and because they're cheap enough, you can have a new one installed every couple of years. I use Magnaflow pretty much on all my vehicles except my 1955 ford (company) truck. Only because I want that LOUD "look at me" flowmaster sound. Plus I in this case, I think the flowmasters do sound better with my blower. Like I said, either will be a good peformance choice. Tim | ||
