if i ran straight pipes off the headers back into a set of bassani mufflers would i notice a hp gain?
also will it mess up my valves or plugs?

you need an h-pipe in there to equalize the exhaust pressure. if you ran straight through muffers (which offer no back pressure at all) then you dont need an h-pipe.

no you will not gain any hp by deleting your h-pipe. you will gain hp from putting on aftermarket mufflers cause the stockers are junk
