hawks sinister 4"
heres a quick video of the hawks sinister exhaust i installed, i will be adding a dynatech split flow muffler hopefully this weekend, working 350 miles from home makes it kinda hard to finish my camaro, engine is a 406 sbc with afr heads 1.5 roller rockers, comp cam xr274r solid roller, vic jr intake, holley 750, dyno don headers. thinking about switching to a 1.6 rocker do you think it will make much of a difference? btw fit is great on the sinister exhaust
