Thanks again for purchasing your new 409 stainless steel Pypes Performance Exhaust 05-10 Ford Mustang H/X-pipe. Please be sure to confirm all the components in the kit were received in your shipment before beginning installation. These kits will include your new x-pipe, two front legs with 02 bungs, and two HVC10 band clamps. If you find any component missing, please contact our office at 800-421-3890 for replacement. For a quicker and tighter installation, air tools are recommended. Technical assistance is available both online at www.pypesexhaust.com or 800-421-3890.

This x-pipe will install directly to your HDR55S headers.

1. Slide the two front legs into the expanded portion of the xpipe. The two provided HVC20 band clamps will seal these joints.

2. Now install your new x-pipe. Begin by sliding the hanger through the factory mount and connect the rear portion to the factory mid-pipes using the band clamps just removed. Snug the bolts but do not tighten. Some 08-10 vehicles do not have the transmission exhaust mounts, thus the hangers will ne be needed.

3. Bolt the ball and socket connections together with the provided hardware.

4. Once you have adjusted properly, tighten all the clamps and the flanges. Now install the 02 sensors.

5. Note: This set-up can easily be converted into a street legal catted x-pipe using Pypes CVM10K cat kit. Simply remove the front legs and cut off 8-1/2” of pipe, install the cat kit and clamp back together.

This h-pipe will install directly to your HDR55S headers.

1. Slide the two front legs into the expanded portion of the H-pipe. The two provided HVC20 band clamps will seal these joints.

2. Now install your new H-pipe. Begin by sliding the hanger through the factory mount and connect the rear portion to the factory mid-pipes using the band clamps just removed. Snug the bolts but do not tighten. Some 08-10 vehicles do not have the transmission exhaust mounts, thus the hangers will ne be needed.
