I have a 91 TT with the stock exhaust. I'm in a state where their is no emissions laws so what would be the best set up with diameter of piping should I take out the dual cats and go straight pipe, or will I lose back pressure and I don't want the car to sound like a high pich rice rocket. I have a guy who can do all the custom piping for me i just have to give him the info.

Your turbos keep enough backpressure. Also, your turbo keeps the "high pitched rocket" sound out. Turbos muffle exhaust quite a bit. It wont be a problem. 4 bangers sound like high pitched rockets....Not sexy z's.
