Makes a perfect set with other Kooks performance exhaust components.

    i have Borla Atak 3 inch - looking for mufflers to mate up with gt350 rear valance (obviously my Ataks won't), will these work for this purpose? Want to keep exhaust system 3 inch.

    If I were to get a gt350 rear valance and put it on my GT could I use this on the GT? I want the corsa Double helix but the duel exhaust tips that come with the extreme cat-back won't line up with the gt350 rear valance which I find to be a far better looking quad tip setup than the roush rear valance. I wan't my car to be one of a kind and the sound to be too

    • The Kooks axle-back exhaust kit will be designed for the 2015-2018 Ford Mustang GT350 only. and would require the use of Kooks Long-Tube Headers and 3" Catted X-Tube.

      Unleash the beast!

      Perfect for the GT350. Its a big upgrade from the factory exhaust. It has the perfect sound that will really make your 350 stand out.
