![]() I completely agree with everything recommended except for one thing. I don't believe that back pressure in the exhaust is ever a positive factor. Now, velocity in the headers will help evacuation of the combustion chamber and can improve power even if more restritive than larger headers in some cases. Restriction (to any degree) in the pipes and mufflers after that never helps anything. That in a nut shell is my unvarnished opinion. I run 2 1/2" pipes with 3 chamber FlowMasters for that reason with a mild 306 street engine.
