I was driving to work the other day and I drove past a Tuffy Muffler place - there were no cars in there so I stopped off to talk to the guy. I said I was thinking about putting a 2.5" dump pipe on my Golf GTI and had he had any experience with how they performed.

He told me that a dump pipe alone will do nothing because then it goes into the stock restrictive pipe. This was contrary to what I have heard and read everywhere else which suggests that the only restrictive part of the stock system is the dump pipe.

So he went on to say that to gain any benifit I would need to fit a full system and he could do it for..... wait for it .......

$3000!

That's right - three THOUSAND dollars.

Can someone please clear this up because I know that someone else on this forum went to Tuffy for their dump pipe and all the other resources I have investigated suggest that only a adump pipe is needed for a significat gain in power, particularly if the car has a GIAC chip / boost. Mine is stock at the moment but a chip is on the way in a few weeks.

Was the upgraded dump a noticable improvement?

Have you dynoed it before and after?

Ehat extra KW are expected?

I had a full 3inch turbo back system done for less than $2000.

It's common to fit a larger down pipe to the std system in Europe, The exhaust flows pretty good, consider it will allow a chipped car to make 200 hp. The larger DP lets the turbo spin up earlier.

Mmmm, on sunday we'll get our dump pipes out and compare sizes...

gpk_gti - how much was your dump pipe and fitting from Tuffy in Alexandria? And can they fit it on the spot quickly or was it a bit of a process? The Tuffy I went to was in Newtown.

I've put on a full 2.5" turbo back with new rear box and the car goes so much better. Probably 20% more power I'd guess. Spools up quicker and is not that loud at all - just a nice rumble.
