I currently have a stock engine with most of the usual bolt ons that is a street car. I have a ported exhaust housing, Kirban's 3" downpipe /3"testpipe/hooker duals setup. My question is what horsepower might be gained with a THDP, or the Mease Downpipe? Is stainless steel better than mild steel with HPC coating inside and out? Thank you.

Since you already have the three inch pipe I would not bother changing it.
Remember "there are many ways to skin a cat, you don't have to copy one."
One of our good friends runs 115MPH through the stock elbow and 2 1/2 inch DP. The motor is totally stock.

Thanks, John.
I think I was hoping that moght be the case. 115 is greater than my dreams at this point. Regards, Gary L.
