    Since y'alls description is fairly vague at best. Is this setup for a single inlet? Cars turboed so I need something that is single in dual out..

    Rockybobby

    • The Magnaflow Competition Cat-Back Exhaust is comprised of two completely separate pipes. So this cat-back is dual in/dual out.

    the kit explains is intended to bolt to a 3"midpipe. so does this mean any midpipe that is 3" not magnaflow specific? will it bolt with the kooks 3" catted x pipe?

    JohnathanL

    • The Magnaflow Competition Cat-Back Exhaust - 3in. (05-09 GT, GT500) does not need to bolt up to a Magnaflow specific midpipe. As long as the midpipe you want to use has a pipe size of 3" you can bolt the The Magnaflow Competition Cat-Back Exhaust up to it.

      Completes the package

      I have a fairly heavily modified GT, cold air, TB, intake manifold, cams, long tubes with a 3 inch H pipe. But stock 2 1/2 inch over axle pipes and some axle backs. I really didn't like some of the sounds it was making in the low RPMs. These pipes changed all that! Gave me a nice consistent deep growl, I love it! Really lets her flow and completes the package. The guys at the shop said they went in nice and the instal only cost me a 137 bucks. I would recommend this set up to anyone with a 3 inch H pipe. Oh, and AM had it to me in 3 days!

      AWESOME EXHAUST!

      Exhaust sounds GREAT! Love the look of the 4 inch stainless steel tips. If you are looking for a deeper rumble sound for your mustang then this is the right exhaust to get!
