@FirebirdBuco if tis a carbed engine then u dont need back pressure but with open headers on a fuel injected engine then no your loss tons of power and tq
@bigballa97 thats funny cuz my 95 Z28 gained 5hp with my cut out open? must have been a faulty dyno...the idea of open headers burning or warping valves is a myth
@FirebirdBuco burnt valves are caused by rapid cooling, if you ran open short length headers you would run that chance, becuase the outside air has a shorther route.
@bigballa97 oh and by the way nice car lmao....a cb7?? i hope that video you uploaded was a friends car cuz it sounds like complete ass..i bet it runs an 18 sec 1/4
you realize your car hates you right now right? lol running it with open headers screws up the compression soooo much!

@lawdawg1400 yes please explain how this screws up compression?

@FirebirdBuco its has no exhaust back pressure which in turn lets all your internal compression get sucked right out (and no that aint a good thing)
