Description: 2-1/2” off-road H-pipe for 1999-2004 Mustang 4.6L GT, Cobra, Mach 1.
OFF-ROAD RACE USE ONLY!! This product is not intended for use on public roads, and is illegal to use on public roads. It is recommended that the customer use MIL eliminator part number 129-1675, or equivalent, to avoid the vehicle from running improperly.
Instructions:
DO NOT TIGHTEN ANY BOLTS OR CLAMPS UNTIL THE LAST STEP!!
1) Remove the 4 oxygen sensors from the original H-pipe. Remove the original H-pipe from the car, unbolting the system at the manifolds (or shorty-headers) and at the flanges at the middle of the vehicle. We recommend using a lubricant of some sort on the nuts for removing the pipes. Leave the existing rear extension pipes, mufflers and tail pipes in place unless you will be installing another replacement system.
NOTE: you will need to re-use the manifold studs and nuts to install this system. Hardware is included for bolting the rear of the system to your existing exhaust system.
2) The driver’s side pipe is the longer of the two pieces of the H-pipe. The front of both pipes is the end with the oxygen sensor nut nearest the end. Install the driver’s side of the H-pipe to the driver’s side manifold using the original nuts.
3) Repeat step 2) for the passenger side pipe. On the passenger side, you will need to use the included gasket.
4) Connect the two pipes with the 2-1/2” clamp.
5) Bolt the H-pipe to the existing rear exhaust system using the 3/8” x 2-1/2” bolts, nuts, lock washers, and two fender washers per bolt hole on the flanges.
6) Install the 4 oxygen sensors to the appropriate oxygen sensor nut of the H-pipe.
7) Tighten all clamps and bolts. Check for clearance, leaks and rattles.
