most of the info i have read stated that a 4" exhaust can be good for up to 500 horsepower. how high are you planning on going?

i put on a 4" tubo back system last week, no muffler and no cat. Love it!
The turbo sound from the exhaust sounds awsome and i noticed an improved MPG on the highway - about 2-3 mpg better. Dropped my EGTS also.
