409 Stainless Steel 96-04 Ford Mustang GT Offroad H-pipe
for HDR53S

Thanks again for purchasing your new 409 stainless steel Pypes Performance
Exhaust 96-04 Ford Mustang GT H-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 h-pipe with 02 bungs and
installation hardware. If you find any component missing, please contact our
office at 800-421-3890 for replacement. Installation of this kit will require a
few simple hand tools, a cutting device and penetrating oil. For a quicker and
tighter installation, air tools are recommended. Technical assistance is available
both online at www.pypesexhaust.com or 800-421-3890.

1. Begin by disconnecting your negative cable from your battery, as
you will need to unplug and remove your O2 sensor harnesses. Place the
vehicle on a lift or four jack stands at maximum height. This will aid in an
easier installation. Note: Make sure to support your mid-pipes just past
the connection point between the factory h-pipe.

2. This h-pipe is designed to directly connect to P/N HDR53S
long tube headers to a factory gt style catback. The center “H” will be
clamped or welded to the desired width. The 02 bungs should angle up
towards the floors of the vehicle.

3. Make sure all the ball and socket connections are tight before
starting the vehicle.

Helpful Hint:

The use of adjustable flow tubes like our PFF10K
will aid in the hook-up of this H-pipe.
