      The MRT axle back exhaust kit w/ tips are made to endure the elements for sure. The sound is aggressive and definitely unquestionably unique. The install was real simple and only took couple hours, It's a win, win all the way around I'm impressed. - Dave, Verified American Muscle Buyer

I actually had a pair of Borla 2-1/4"
