Zepp21 here the deal with the Bola($600 Atlantic British), the thing is st/steel so it will out last the life of you truck. As for MPG and extra power you?re not going to see much with the cat back part.
How ever you may or will with a full system.
I personally think the NRP is the best hands down and if I had a more understanding wife and the cash $1400 I would have one on my truck right now.
Here the gig, the NRP Y Pipe, and this the bit that gives you more power, is a 4 branch pipe set up taking the gas from 4 cylinders in to 4 pipes at the manifold to 2 pipes at the connection to the manifold and in to 1 pipe just before the Cat. Thia allows for greater flow instead for the standard 4 it to 1
Also if you look at a standard steel exhaust pipe, every time there?s a bend you will see a belly. The pipe has to be miss shaped to make the bend this in effect disturbs the flow of gas and reduces the bore size. On Borla and NRP there is no Belly the diameter stays the same. So with the 4 branch and the bellies missing the gas has a fast freer flow with back pressure to get out = more power and more efficiency.
As for the noise, that?s up to you they all sound pretty tasty. For me the sound on my fabricated system sounded great, but it?s a bit long in the tooth now so I?m getting a resonator fitted.
AH yes and all this is relevant to racing car IE Rally, Touring etc
You don?t work for ZEP by change??????

Zepp21 Dont waiste your time replying to some people in this forum, they just love to get attention while objecting to almost everthing others have to say or want, nothing wrong with rovers or any vehicle having a little growl, or a loud growl if thats what you like.

First of all, the bends that you describe (without "bellies") are called Mandrel bends. "Mandrel bending is a widely misunderstood bending term. Many people and even some bending companies refer to the bending dies as mandrels or shoes. Technically the mandrel is a part of the tooling set but does not exist in most bending applications. The mandrel actually goes inside the tube and is held by a mandrel rod to support the tube at the tangent point of the bend. The mandrel is then extracted after the bend is complete or within the last few degrees of bending. This requires a machine with a bed longer than the tube being bent and strong enough to support the forces against the mandrel."
That is why the Borla and NRP exhausts have no creases in the bends, because they Mandrel bend thier exhaust. It's expensive and only REALLY needs to be used in racing applications. Mandrel bent pipes for a Rover is complete overkill and you will most likely see no benefits from the added flow in a street car.

Hey I agree with you, there's nothing wrong with it...It's just stupid and you look like an idiot pulling away from a light making all kinds of racket, sounding like a race car while your 0-60 time is that of a school bus. Nothing more retarded than a slow ass car that some moron has made LOUD so it sounds like it's fast. But it's your truck so do whatever you like.
agro1 said:
Why would it be stupid?
why would a "LOUD car sound like its fast"? if its fast, then its fast, if it is slow, its slow. simple as that.
there is plenty of fast cars that are whisper quiet.
Who said anything about "making all kinds of racket" ? only a growl was discussed.
and of course he'll do whatever he wants

Ok lemme rephrase. Rovers are slow, everyone knows that. So giving them an agressive sounding exhaust makes no sense unless you are a poser trying to make a slow ass car sound like it's fast.KngTgr said:
And a fast car that is quiet is done so for a reason. To be a sleeper. Like an S55 Benz. Very quiet, yet very fast and comfortable at the same time. It's called being understated and not drawing attention to yourself. But hey, if you or anyone else want people to look at you rumbling away from a light at a snails pace, go right ahead, it looks and sounds stupid.
Why dont you understand? LOUD does not mean FAST, nor it makes a slow car fast, nor it makes it look or sound fast, it's just that, LOUD, some people like it loud, others not so loud, and others quiet, now sleeper while fun, are also deceiving, if you are into that, fine, I dont mind. if a person is a poser for having or liking a strong, slow, LOUD vehicle, I dont think it applies.agro1 said:

Well, I wasted some time and made a recording for you but, looks like I can't post it since it's a wav file.
I have a Borla on my truck but, I didn't buy it because it was loud. I bought it because it was Stainless inside and out and my stock one was rusting out on me.. Yes, it's louder then the stock one and I can't say that I like that although it doesn't bother me.. It certainly isn't honda civic grapefruit launcher loud though or even dual exahust ford/chevy/dodge truck loud either.. It is louder then stock more so if you run a higher flow cat.. My new cats ( I crushed the pass side one ) are aftermarket ones and they seem to flow better then the stock ones did. Of course I drove around with my cat halfway crushed in for a while till I finally finished it off once and for all and it's internals came apart and choked the rest of the system so it could just seem like they flow better..
I put up with the noise to get the longevity of stainless and the price wasn't bad either.. Now I just have to keep from crushing it..
I do agree with Argo to a point about the loudness factor however, some times things come down to pros and cons and which one you view out weighs the other.

And now you say loud is the intended result ? Make up your mind dude. As Eric stated, the choice to go with the Borla system was becasue it's stainless and will outlast the truck. That's a good reason to do it. But to leave the stock system and just swap out mufflers to make a SLOW CAR loud is stupid. Now I'm beginning to think I'm the stupid one for even debating this with such a moron.
Well I agree with you, only for a different reason.agro1 said:...Snip...Now I'm beginning to think I'm the stupid one for even debating this with such a moron.
Why would I have to make up my mind? and about what? I still have the same point of view that I had from the begining.
some people might find a low growl soothing, and that makes for a more pleasurable driving experience, isnt that good enough?
I can't believe that this is still being discussed. Agro needs to come to grips with the fact that there are people that have aftermarket exhausts. In my opinion it has created a must better torque curve on school bus the as well has increased my mpg, regardless of the increased resonance.

I never once debated that, Chris. You said "In my opinion it has created a must better torque curve on school bus the as well has increased my mpg".DiscoMastiff said:
Would you mind posting the amount of increased torque you have measured, how you measured it as well as the increased fuel mileage and exactly how you measured that ?

i owned a Borla for a Ford Focus that i turned into a am rally car. i really liked it and would consider buying it for my truck. It made everything feel very smooth. a very nice low grumble. honestly, maybe a little loud for a trail though.
Well, I didn't notice any horse power gains or great mile per gallon increases. I can say that I did notice that my engine runs cooler... My temp gage reads a little lower now then it did before. My bling, bling, hey look at me, snorkle also helped lower the temp gage a little bit too... Not that it's a huge difference but, just what I noticed after putting that stuff on.. If anything I would say that I am probgably burning a little more gas then before but, I never keep track of that.. I just fill the thing up when it gets down to a 1/4 tank and leave it at that.
If you were looking for the scientific or exact figures on the torque sorry to dissapoint. Maybe next time when you are out having lattes at the Pannikin and I drive by don't foget to mention to yourself how there is Nothing more retarded than a slow ass car that some moron has made LOUD so it sounds like it's fast
See you around Agro.
