anyone modified the exhaust on the R36?

[amt]

Looking for experiences on those that have modified the exhaust on their R36, not much info available for this model. TIA

[GHW]

Go to youtube. Be prepared to pay insane money for a couple of kw's.

I have been going through this whole saga for weeks now and the ones that are doing cat back only and gaining well not much. Speaking to a few performance places and other who I won't mention to get any real gains you need to change the cats to real high flow cats (there are high flow cats and there are high flow cats) The problem with changing them on the R36, is the the oxygen sensors are situated after the cats so its going to throw a light or two or maybe even make you walk home.

So putting a 3 inch system from cat back to me sounds a waist of time when what really is resticting your flow is the cats, I have been for a drive in a cat back r36 and sure its sounds a little better but performance ???

I have asked VW and other people who have experience with VW's and the likes of you plug in ECU guys and no one can at the moment as far as I know disable the oxy sensors.

So I have decided just to put my car on a dyno on monday check the KW and torque etc, get the ECU done then put it back on the Dyno, and hopefully gain something, if not the ECU fella will refund the $$$'s.

If any one knows different please respond.

Ohh if you want more performance I was quoted 18g's for twin low pressure turbos.

As changing the exhaust gains very little for high cost I'm considering changing just the rear mufflers just for a hopefully better note without drumming

R36 + 18G = second hand 911........

I am looking at changing my Evolve exhaust back to stock. I have specially custom made high flow cats for the R36 sedan. If anyone is interested, PM me and we can do a swap deal.

But what you said is through, the cat is actually one of the main culprits restricting the flow.

Sloutch, does the high flow cats trigger off the warning lights due to the oxy sensors ?

[gead]

sloutch, would you care to share your reasons?

[Rocket36]

too loud for his wife... lol

even the guys at Evolve thought it was a funny reason.

[Tim]

cant help myself

I've read that the exhaust is already very good, that is flows well, better than the R32 which alot of people make the mistake to think its the same but I've been read its not. Your right gains for buck aren't worth it. However a sweeter exhaust note would be welcomed. Any recommendations on rear exhaust that suits a prestige car?

Yes, it does trigger off the engine warning lights. However, correct me if i'm wrong here, i reckon after you install the cats, bring it to a tuner and they will be able to remedy that.

Well, to each of his own preference to be honest. For me, like what i told many people, i have owned Evos, Skyline GTRs, i wouldn't mind having that exhaust note on those cars but on a nice VW R36, i think it is a little loud for me. I know most people love the exhaust note but i guess i'm just over it.

At the moment i'm looking at changing the evolve exhaust back to stock. So for those who are interested in the Evolve exhaust, feel free to PM me and we can work something out. Thanks.

So far the People who are doing my tune and others I have spoke to are telling me it can't be disengaged other wise I would have had it done a long while ago.

If any one knows different please let me know would love to have high flow cats which I'm sure will give a much nicer note too.

I have a Gruppe M CAI on my R36 and gives it a nice growl, but as for their design, mmm! needs work.

The Gruppe M by itself does give it a nice note. As far as i know, getting a good high flow cat is rather expensive. The one i have is a high quality 100 cell cat. It does make the car sound different as compared to the other R36 i met.

Your right there the high flow cats I got quoted and sounds about right with the 100 cell thing is approx $400 each. So with your cats Sloutch when they triggered the light on your dash did it effect the how the car ran ?
