Exhaust System Installation
Double Helixx X-Pipe
2016 Shelby GT350
PN 14347
Factory Exhaust System Removal:
1. Starting on the driver side, measure 14 ¼” away from the end of the tunnel resonator heat shield on the stock
resonator, following the inside profile of the exhaust pipe, and mark the pipe. (Fig. A & B) The tape measure
should follow the bend profile of the pipe. Next, on the passenger side, measure 14 ¼” away from the end of
the tunnel resonator heat shield on the stock resonator following the inside profile of the exhaust pipe, and
mark the pipe. (Fig. C) Again, the tape measure should follow the bend profile of the pipe. 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. Slide the now cut rear muffler assemblies as far rearward as allowable. Using a 15mm deep socket and 3/8”
drive ratchet loosen the two sleeve clamps at the cat-back connection point. (Fig. E) Both nuts must be
loosened in order for the clamp to fully disengage. Slide the stock x-pipe rearward and remove it from the
vehicle. (Fig. F)
NOTE: The use of a soap and water solution on the rear axle pipe and muffler hangers may aid in sliding the rear
muffler assemblies rearward
3. 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.
