oh and like said, a strait pipe exhaust is illegal, and extremely obvious. leading to getting caught in no time if you're not carefull.. and penalties for not running a catalytic converter is pretty harsh in most states

i think i might get that cutoff switch for the exhaust so you can just switch between them at will. hopefully by then they will work the kinks out of the electronic onesoh and sean, will going straight piped really add 10-15hp? your not losing too much backpressure? on a bt'd a4 i could see it helping but what about a k04 (running between 16-18 psi)

Dont be a d!ck just get a high flow cat at least, your a4 is no lambo anyways...no need to punish the earth over trying to get it to be at most a mustang. This coming from san diego...so ya. Cut that stuff out. If you want a fast car, buy an emissions semi-friendly burly car int he first place.

loosing too much backpressure? haha, no, not at all.. in regards to hp on a turbocharged engine,zero backpressure is what you want. there is no problems with having zero backpressure.. i've heard though, that with some internally gated turbos, like the k03/k04, you will loose a little bit of low end torque. but still on those turbos. less backpressure means more hp.

it is insanely loud. i only have 1 muffler on my techtonics exhaust so i took it off and it sounds like a turbo diesel at low end and a dragster when you floor it. at night if there's a cop within a mile or 2, he will hear you.
here's a vid of The Russian's car stragiht piped. mine actually sounded louder than his (i think cuz of the test pipe)

for what his current setup is, PC-16 w/ stock exhaust, yes. he's going to get A LOT better flow up top from removing the stock exhaust.. now if he was going from a borla catback w/testpipe, he would probably net about ~2hp..
loosing too much backpressure? haha, no, not at all.. in regards to hp on a turbocharged engine,zero backpressure is what you want. there is no problems with having zero backpressure.. i've heard though, that with some internally gated turbos, like the k03/k04, you will loose a little bit of low end torque. but still on those turbos. less backpressure means more hp.

really...thats good to know. definitely getting that electric exhaust cut off then. if for nothing else, just to scare small children and old people[8D]

So I plan to do the dump pipe anyway but have it bolted in place with wingnuts so I can open it up at the track to help the turbo spool.

do you realize how little my test pipe contributes to the amount of crap that is in our atmosphere? go cry to someone else
