2.5 or 3 inch exhaust????

My long tubes will be done soon, and i was planning on running an X-pipe to two flowmaster 40 series, and turndowns. (all 3 inch)

My friend thinks 2.5 inch would be better..he says ill need some restriction.

2.5 will be fine unless you plan on doing some heavy mods in the future...youll have a lil more ground clearance with the smaller pipes too

I have a full 3" system from the collectors to the back of my car. Sounds great with some great flow
