installing an H-pipe

[mus1994stang]

i have an offroad H-pipe coming soon. how hard is it too install on an 02 GT. im not sure if i want to wait until after emissions to install it. do i need 02 extenders, i will have MIL extenders. do i need anything else?

thanks guys.

If the pipe is O/R, then I'd wait till after the emissions check to do it since the car will probably fail with the O/R pipe on.

If the pipe preserves the locations of the O2 bungs you'll likely just need a couple of MIL elims for the back sensors, no extensions.

Putting it in isn't hard in theory but some of the fasteners can be a bit of a bugger to get at (especially the right-side manifold flange...) Make sure you have lots of PB Blaster and lots of extension, swivel-joint and socket combinations

What about the front O2 sensors? do i need to do anything with those?

Nope, just the rears.

got the pipe today, but the front 02 sensors wont reach cuz the holes are farther back then stock
what should i do??

 

[Mirrahasmycar]

they should reach

They should reach, they may be hard to get on, if you really can't get you can add more wire by splicing some in, or getting a longer wire from the parts store,

How to instructions here

I just replied to your PM.

I'm not sure if the pic below is the right one but see where the O2 sensor wire joins a larger wire bundle? Look there on yours. There was a clip on mine that can be cut/removed to give another inch or two.

The installation is a snap. Have 2ft extensions for your socket wrenches and swivel sockets (deep). And you'll be all set. Oh, and spray the manifold bolts with WD-40 or preferably "Liquid Wrench" to help them come off if they are stuck.

I installed my Mac Off-Road H-Pipe myself as well, but I used a friend of mine's hydraulic lift in his garage (yeah, that's right, he has 2 lifts actually). I don't know how the installation will be if your car is just on jackstands, but it could be a real pain wil the small space, lack of light, and general inconvenience.
