    Are these available with cats?

    • 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

      Worth it!!

      I was wondering if the sound would be sufficient and it absolutely is. I would compare the sound to going full throttle under a bridge with an axle back, to hitting the throttle now anytime sounding twice as loud. The performance is definitely there, noticeable difference. Highway is fine coasting and not to loud inside the car in 6th gear. In fifth your gonna hear it, very loud. I’m very pleasead and wanted it loud and aggressive. Recommended!
