u kinda lose a little power on the top end with the twin loop, but in the low revs the twin loop is more responsive compare to the canon muffler, but its really up to you, which one u prefer, canon muffler has lots of power in the top end, but low revs its not responsive, its not much power u lose at the top end with the twin loop prolli 15% only,
