I dont what car you have exactly but lets just say alot of burnt up ****. You know all those things directly in line with the lil holes the come out of the head... Yea those, they will be melted and will be flipping off you off in no time. Oh yea, forget about ur paint job... =) Just dont try it unless you have some nice fire extinguisher system in your hood that will automatically go off as soon as your engine bay catches fire...

i've started up plenty of engines with no exhaust manifold whatsoever. its loud as ---- and shoots fire out the ports. dont do it for long periods of time.

I've driven hondas with open manifold for weeks at a time with no "burnt valves". its horseshit.
