Im in NYc

BigJack,I got some more info on the exhaust system from Henry. It's 3" and from header collector back it's 650 bucks for the set on a roundy round car. That includes custom install. Henry Jr.fabs them out of 304 stainless and on a typical small block mod dirt car they have seen dyno #s that average 19-20hp and 18-19tq. with hp peak at 30 over other systems. They made a set for Matt Shepard's car.

Thanks BigJack.. you explained it well. My car is snappy with the upgrades,but maybe I expected too much. I thought it might be a bad kit install and had it checked twice. They advised it was done right. My kit cost $600.00 and the install was $200.00.

Hey do you know a guy named Steve Joslin aka Fathead
