    I have the Corsa Sport cat back exhaust. With this do I need to get a mid-pipe? Also what does the aftermarket connect mean?

    • Yes, this kit is compatible with your Corsa sport Cat-Back exhaust and will definitely be a great addition to the GT Mustang! This kit will work without mid-pipe and the aftermarket connect means that it works with aftermarket exhaust systems rather than the factory exhaust set up.

    • This is only designed to work with aftermarket cat-back systems.

    Will these headers direct fit to AWE Touring Edition Cat-Back with H pipe? If not, is there another catted header on AM that will? Thank You.

    • The AWE Touring Edition Cat-Back Exhaust, item 397439, has a 2.5 inch stepdown, meaning it will not be compatible with these long tube headers. You would just need to get an aftermarket catback system that has a 3 inch connection and you should be good to go.

    Are these headers compatible with the MBRP Street XP Series Cat-Back Exhaust w/ H-Pipe?

    • The Stainless Power 1-7/8 in. Long Tube Catted Headers will not pair up with your MBRP Street XP Series Cat-Back Exhaust w/ H-Pipe because of the length of the mid-pipe. The long tube headers will require a "shorty" mid-pipe in order to connect correctly.

    Does these require a tune or would it just benifit the car more? 1 answer
    I have noticed that a lot of the headers state that they are for off road use only but this set does not. If I have these installed on my GT will I be street legal (I don't live in California) and will I have to be concerned about the check engine light coming on or any other issues with the car's computer system? 1 answer
