I would get a two brothers it is awesome and sounds great you can also control the sound level with core inserts this pipe work better and fits better than the other two that I had I would stand strong for the two brothers good luck
I have a Trinity Stage 4 slip on and i am impressed with the power. If i were you i would look up some dyno sheets and compare some of the different slip-ons. i will agree with the two brothers though. heard nothing but good from people with them.
