    Will these work with the 3" Borla Atak Catback?

    RyanL

    • The Stainless Power 1-7/8 in. Long Tube Off-Road Headers are designed for use with the Corsa, MBRP or Stainless Works Factory Connect Cat-Backs. This can work with the Borla 3" system but may not line up perfectly.

    Are these available with cats?

    Admiral

    • We offer a catted version of the Stainless Power 1-7/8 in. Long Tube Off-Road Headers but they are not designed to work with an after market exhaust. We have 2 different options. One set will work with the 2015-2017 GT Mustangs with Stainless Works 3" Cat-Back and the other set will work with 2015-2017 GT Mustangs with Factory 2.5" Exhaust. You can find both options here: https://www.americanmuscle.com/stainless-power-catted-lt-headers-sw-1516gt.html Or https://www.americanmuscle.com/stainless-power-catted-lt-headers-oe-1516gt.html
