        Will this fit on my 2019 Mustang GT with my 3in Corsa Xtreme Catback?

        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.

        will these fit a roush axle-back with the stock resonator? if not, which set of headers would?

        • This kit would require an aftermarket cat-back exhaust. For factory exhaust, you would need something like this: https://www.americanmuscle.com/stainlessworks-catted-lt-headers-oe-2015gt.html.

        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
