Hello, I recently had some head gasket issues, so while I have the head off for machining I figured I would also get a mild port and polish. It was bench flow tested and had a 30% increase in flow! Now I am looking to my exhaust, I currently running a pro circuit head pipe with a muzzy slip on. The head pipe is not much different in size to the stock header except the welds are flat on the interior, so would I benefit moving to a full system or maybe a better flowing pipe like an hmf?? Sorry for the long question.
Oh and by the way, it's a 416 11:1 comp wiseco, stage 2 hotcam, 450r carb, and of course mild p&p thanks
