Does anyone know if these really work? Would I see power gains without changing the exhaust?

The header is fine. Not much of a gain if the flow is stopped up after freeing it up. Just do a custom mandrel 2" at the local shop. Should be decently cheap and toss on a decent muffler. DONT GO RICE please no weed eater man.
