Inliners International Forums General Discussion Hi Performance mufflers for chevy 292..any reccomendations??

I like the sound of a six thru a single exhaust but your build sounds like at least 250hp, so to me you're on the ragged edge of getting away with even a 3" single.

2" duals, glasspacks with a H-pipe might be nice and are ok to 250-280hp or so. Maybe what Langdon meant is if you get glasspacks, get the kind that are perforated and do NOT have louvers sticking out into the flow.
