For a camaro with a 5.0 in it, should I go with true duals or 1 single pipe all the way back? If your opinion is the dauls, how big should I go, and if your opinion is a single pipe, how big should that be? thanx

 

well me and my dad are probably gonna do the exhaust ourselves because we have a pipe bender and all of that, so we are going to try and tackle it by ourselves...but for dual straight pipes without cat and 2.25", is there enough backpressure?

 

You will have plenty of backpressure because you don't have a mandrel bender and you will have kinks in the system. Just buy a 3 in exhaust and you will be fine. Also, you won't lose any ground clearence which you will with a set of duals.
