Exhaust size!!?

[elCrillo]

What size do you have on your exhaust!? I'm building a completely new exhaust system with catalytic converter and all, do you think I should build in 2.5 "or 3"? The engine is standard with larger intercooler, another manifold and a chip in the future ...

2.5 is good for your setup. 3 is used if u have heavy tunned engine.
