3.5in exhaust, how bad is it?

Should be good to 500 shouldn't it?

Single 3 is good to around 500. 3.5 can support more.

A friend of mine has made 825whp with 3.5" exhaust. Not saying it wouldnt pick up power with 4" but it made close to 1K crank with single 3.5.

3.5" will be fine. Ive ran overkill exhaust and there was minimal difference from a set up closer to stock.
