Your car will sound cool and get everyones attention but thats about it. This is why alot of turbo cars remove their car/testpipe at the track and run open downpipe. The less backpressure in a turbo car the better. Take a look at AMS or DogBoxracing's EVO's the exhaust comes off the turbo and goes out right thru the side of the front bumper, the total exhaust is about 2 feet long.
