anyone know if I can get a mbrp, or borla muffler that can be fitted to my maggie 16612 kit.. it's just not loud enough at all, and I dont have 500 bucks to buy a whole new kit right now.

 

You can always get rid of the cats and run 2 high flows. You're probably going to have a few guys come in and tell you to try the Dynomax Bullets. They should be louder. I have no idea how loud the MBRP is but the Borla is probably about the same as the Roush since Borla makes Roush. It will sound good but I don't know how much louder it will be over the Magnaflow.
