      Improves Exhaust Flow. Ford actually did a nice job on the S197 Catalytic Converters, but the stock H-pipe could use some improvement. That's where the Ford Racing Cut and Clamp X-Pipe comes into play. Designed to balance out the exhaust gas pressure in your system, this X-pipe will help improve exhaust flow for more power and sound.

      Reuses Stock Cats. The installation of the Ford Racing Cut & Clamp X-pipe requires cutting and removing the stock H-pipe, and reuses the factory catalytic converters saving you money. Clamps and instructions are provided.

      Quality Materials. Constructed from sturdy 2.5" mandrel bent T-409 Stainless Steel tubing the Cut & Clamp X-Pipe will improve exhaust flow and last a lifetime.

      Application. This Ford Racing Cut and Clamp X-Pipe is a specifically designed for use on the 2005 to 2010 GT and Bullitt Mustangs.

        Ford Racing

        I did the cut and clamp, no leaks in the exhaust but I’m going to have it welded in later, probably the best way to install it. Overall a good product.

        Don't buy

        Did not fit.They sent me a replacement that did not fit.5 hours I will never get bake , and irritated my not so good bake for several Days.Also so spend extra money on tools that did not help install at all.Pipe angles all wrong and would not line up, even with all pipes very loose.Will not buy ford performance ever again. P/S American Muscle Made good with pypes X pipe fit perfect and sounds great and only took about 1.5 hours to install. VERY HAPPY WITH PYPES X PIPE!!!!!!!!

        Ford X-pipe

        I added this X-pipe (suggested by American Muscle) along with a Roush Extreme axle back looking for quality sound that was not too loud. This combination is exactly it! Installation took a little longer that predicted but it was well worth the wait.

        X PIPE POWER

        This X-pipe added a nice sound to my S197 mustang and I feel a little more power. Great addition to your exhaust system.

        X pipe for 05 super charged 4.6.

        The X pipe changed the exhaust tone to a noticeable pitch, I have Flowmaster outlaw axle back mufflers. It seems to sound like the newer 5.0. It takes the super charger to a new level. Love the response and the new tone.

        4 2007 GT - TaylorS Installation Time: Afternoon

        Satisfied Overall

        The X-Pipe definitely gives a slightly more aggressive tone especially when coasting but fitment could have been better thats the only reason i would give 4 instead of 5 stars.

      5 Top Rated Questions

      Will I need a tune with the x-pipe?

      • This x-pipe reuses the stock catalytic converters so it will not require a tune after installation.

      With this X-Pipe installed, would an axle-back bolt on exhaust still fit or would it need to be trimmed to align correctly?

      • An axle-back exhaust can be used with this x-pipe without additional trimming.

      Whats the difference between this ford performance cut and clamp and the pypes cut and clamp. Is there any sound difference?

      • The sound will be roughly the same. The quality of the Ford Performance will be better though.

      Would the install of this mess up my future plan of putting a high flow catted x pipe and long tube headers considering you need to cut pipe or no?

      Can i install this on V6?

      • This cannot be installed on V6 models.

      are these x-pipes california legal? I was told by a hole in the wall muffler shop that they are not. I'm thinking of getting these to go with my Borla Stingers. 1 answer
      I just added the Flowmaster 40 series Axle-back to my stock 07 GT and love the throaty grunt they give off. I was hoping they would give a more deep and loud sound than they do. Would this X-Pipe be a better choice to achieve my desired sound, or would an H-Pipe be a better choice? Am I correct in saying the performance (Dyno, MPG and response) is better with the X-Pipe than the H-Pipe? If it helps make my decision, and your answer more informative, I am getting ready to buy the JLT series 3 and Tuner combo from you guys. Thanks. 1 answer
