Exhaust System Installation
Double Helixx X-Pipe
2015 Ford Mustang GT 5.0L V8

Factory Exhaust System Removal:
1. Starting on the driver side, measure 22½” away from the flange on the stock resonator, following the outside
profile of the exhaust pipe. (Fig. A) The tape measure should follow the bend profile of the pipe. (Fig. B) Next,
on the passenger side, measure 23” away from the flange on the stock resonator following the outside profile of
the exhaust pipe. Again, the tape measure should follow the bend profile of the pipe. (Fig. C) Using a chain
cutter or similar device, cut both the driver and passenger side exhaust pipes at the marked locations. (Fig. D)
Place an adjustable stand or similar device under the stock tunnel section of the exhaust for support. Once the
axle pipes are cut, there are no additional stock hangers supporting the tunnel section.
2. Using a 3/8” drive ratchet and 13mm socket, remove the bolt holding down the driver side hanger grommet
assembly. (Fig. E) Once the bolt is removed, push up slightly on the exhaust and slide the hanger grommet
assembly rearward to free it from the rear suspension sub-frame. Rotate the hanger grommet assembly a
minimum of 90° so that it will not interfere with the rear suspension sub-frame. (Fig. F) Place the bolt in a safe
location as it will be reused during the installation of the Corsa X-Pipe.
3. Lower the cut end of the driver side muffler assembly just enough to create clearance between the pipe and any
suspension components. Slide the whole muffler assembly forward to remove the rear muffler hanger from the
hanger grommet. (Fig. G) The muffler assembly will now be free from the vehicle.
NOTE: The use of a soap and water solution may aid in the removal of the hanger grommets.
4. The repeat steps #2 and #3 for the passenger side. (Fig. H)
5. Using a 3/8” drive ratchet and 15mm deep socket, loosen the two sleeve clamps at the cat-back connection
point. Both nuts must be loosened in order for the clamp to fully disengage. (Fig. I) Slide the stock tunnel
muffler assembly rearward to free it from the two sleeve clamps and remove it from the vehicle. (Fig. J)
6. IMPORTANT: Carefully and thoroughly de-burr the stock driver and passenger muffler inlet pipes from any burrs
and sharp edges. This is important as any burrs will prevent the x-pipe outlet to stock adapters from sliding over
the stock exhaust pipes. This concludes the factory exhaust system removal.
