Pypes 409 Stainless Steel Cut & Clamp X-Pipe ('05-'10 GT) - Installation Instructions

1. Before unbolting any part of your existing factory h-pipe, line up the two hanger points on the Pypes After-cat x-pipe with the factory mounting points on the transmission crossmember. Mark a cutting line on your factory h-pipe approximately in the middle of the expanded end of the new x-pipe. This line should be 8”-9” inches behind your factory catalytic converters. Once you have checked the measurement twice, make the cuts through the driver and passenger pipes. Make sure to deburr the two cuts, to allow for a good seal and flow once the new X-pipe is installed.

2. Now you can unbolt the factory band clamps located at the factory midpipes. Once undone you will be able to drop out the cut portion of your original h-pipe.

3. You can now install your new x-pipe. Slide the x-pipe hanger through the factory mounting points, slide on the factory band clamps and install the HVC21 band clamps on the front of the x-pipe. You can now tighten all the clamps.

4. Test drive the car for several miles and inspect for leaks or loose connections. A black residue around a connection indicates an exhaust leak.

5. After around 50 miles of driving, re-inspect for leaks and loose connections.
