will the offset muffler or oval muffler restrict flow? i'd like to keep it as free flowing as possible. so you don't think another hot dog muffler will do the trick? also, i'd like to keep the volume that its at, it's not too loud on idle on and screams at WOT. so you think i should get an oval muffler? offset/centre or offset/offset?
edit: oop, saw you put middle/offset.
