The magnaflow is not going to be louder. The AWE Switchpath (on loud mode) or the Track version will be louder and will sound a lot nicer than the MBRP. I have first hand experience with these three mufflers and the AWE is by far the best.im not looking for a whole new catback. im just looking to change the mufflers in my current mbrp exhaust with somthing louder.
