Drawson,
I don't have the bullet version but rather the race "welded" Dynomax - 4" in and out - about 6" round. Not exactly the same, but similar, sounds great. Bullet probably would be slightly louder - uses less "packing". Anyway, I'm very happy with this muffler and would highly recommend it.
Regards,
Craig
