How to Install a Mustang H Pipe

The Ford Mustang was designed as an American muscle car, one that is meant to be raced. The H-pipe exhaust can help the driver of a Mustang enhance the horsepower of the car. H-pipes provide a combination of perfect air-flow and performance to deliver some extra power to the vehicle.

Instructions

Out with the Old

1

Lift the back of the vehicle with floor jacks and place it onto jack stands.

2

Cut the tailpipe right behind the muffler and pull out the tailpipes. The tailpipe will not come out in one piece. It might have to be swung around before you can remove it.

3

Remove the bolts connecting the muffler to the H-pipe and remove the muffler from the rubber hangers. Spray the hangers with WD-40 if they appear to be sticky, as this could help make the job a little smoother.

4

Remove the bolts that connect the old H-pipe and headers. Using a U-joint on your socket can be helpful, as the area is difficult to maneuver in.

5

Slide the H-pipe from the hangers. Use WD-40 when needed. Remove the O2 sensors from the old pipes.

In with the New

6

Slide the new H-pipe into the rubber hangers. If needed you can replace the rubber hangers, but in most cases these will be reusable. Be sure to line up the pipes with the header flanges and studs.

7

Bolt the new H-pipe loosely into place and hold the H-pipe in place with a floor jack while installing the rest of the exhaust system.

8

Install the pipes that attach to the H-pipe.

9

Slide the muffler into the hangers and use exhaust clamps to hold it into place.

10

Slide the new tailpipe into the rubber hangers and tighten all the bolts in the exhaust system once everything is lined up correctly. Install the new O2 sensors and plug in the O2 extensions.
