        Will my borla arak axle back work with this set up?

        Does the x pipe in this kit work with a borla atak axle back system?

        Can i put theses on without the headers first and just the original stock manifold exhaust?

        • This Kooks Shorty Catted X-Pipe is specifically designed to fit the 2005-2010 4.6L GT and Bullitt Mustangs with either Kooks Manual or Automatic Long Tube Headers installed. It will not install properly without the headers because it is shorter than the factory x pipe.

            Looks like a motor now!

            They sound and look great! I wouldnt want to do it again as I did it by myself with the car on ramps and jack stands...a lift would have been much easier...

            Excellent Product

            Got this as part of the Kooks Header\Catted X-Pipe kit to replace the existing stock exhaust system to improve performance and prepare for a future SC install. Fit was very good and the engine's low end response improved noticeably over the stock exhaust. Got even better when I modified the stock 4.6L tune to incorporate the Kooks header install. Very happy! Took all to the local Ford dealership to install as I don't have the necessary jack stand height to accommodate the install (installed both headers and X-pipe at the same time) but install took far too long due to the kit having missing parts that were supposed to be included so had to work w\ AM to get all straightened out. Otherwise excellent!

            redesigned

            Had an original early design kit without brace on the x, so it has cracked on the weld. Got this one as replacement and it is a new design now, giving a piece of mind about longevity.
