I Have a Question

[FlyTalon]

I have a 98 TSI AWD. I need an exhaust for it and i dont know if i should get a 2.5 or 3 inch piping. I am planning on lightly modifying my car but not heavily. Would 2.5 be enough and would I be able to tell the difference between the 2.5 and the 3.
Thanx
Chris

If you're going bigger than a 16G or comparable turbo, get 3". If you're staying w/16G, get 2.5".
