In response to " Won't the whole Turbo-Back exhaust get rid of your Cat? I would think that would be a dumb move considering the emissions nazis... " in the "APR or Milltek turbo back exhaust?" thread.
most companies, at least the good ones (apr and i think milltek) include a new high flow cat with the turbo back exhaust. As for the apr, not only do they include a cat in the system, but they also have a lifetime warrenty on their prduct, so if anything goes wrong with the cat, they will replace it for free--a pretty good deal considering the cost of high performance cats. i cannot speak on the milltek as i do not have one and dont know that much about it.

Hey there. I am stuck with a decision to make and I can use a bit of guidance. I am planning on getting exhaust on my GTI from the turbo back.
There are several companies which manufacture turbo back exhausts for my car but after reading the pros and cons I am left with my own ideas.
I looked at the design of the systems available for my car and they are quite simple 3in. mandrel bent piping from the turbo back to a can in the rear or in one case just straight piping with no can. The bolt on exhaust runs between $ 1,100.00 to about $ 1,300.00.
I am considering purchasing a good can and having a local muffler shop do all the piping.
Either way I go I need remove one O2 sensor and reflash my ECU to run with only one O2 sensor.
I have asked around and only one other person I know with a GTI has had custom exhaust made for his car. His opinion is to go with something custom.
Can someone shed some light my way?
Thanks.

I'd say stay away from muffler shop exhaust systems for few reasons.
1. Stock 2.5" exhaust will be better the 90% muffler shop jobs
2. Muffler shops do not mandrel bend
3. Most muffler shops do not use stainless pipes
4. Unless you got the cash to get a good direct fit part, dont mess with it. Talk to some other tuners who have dealt with a number of 2.0Ts and they will tell you the stock exhaust system is not bad, it quiet but its not bad.

what if i want an exhaust and can't afford the tbe is there another way to go, could i go cat back and what disadvantages would there be with a cat back exhaust.
I had it done at Brake World in Miami. I have taken all my previous cars there for my exhaust work. The have been doing Brakes and mufflers for approx. 13 years. Same owners and workers from the begining. The 3" going around the axel is a bit tight so I am having them analyze how dumping the exhaust under the car will affect my back preasure. I am thinking of hanging mystock muffler in place to give it a sleeper look when I am parked at the hang outs.GTfly said:
GTfly, I know the gys at the shop I went to pretty well and I trust them. For now.. I have the stock downpipe and cat, from there on a straight pipe from the second O2 sensor back. I have noticed an incredible increase of power. I feel the car a whole lot stronger at low and high rpm. I am setting up a dyno day here in Miami and I guess the dyno will reveal the truth. My last dyno was 218 whp and 269 torque.GTfly said:
