Iknow a woman that owns an 07 mustang v6 that wants to put my Gt factory axle backs on it.....
What would she need for the install aside from the rear fascia? I have no clue on this because I dont know how the v6' s are set up exhaust wise.

 

Okay, basically the V6 has a single exhaust on the passenger side fed by a "Y" pipe upfront (instead of the GT's "H")

The good news is the exhaust pipe between the "Y" and the muffler and the hangers on the passenger side are all the same as the GT dual setup and can be reused.

What she'll need to aquire/add:

An "X" or "H" pipe will need to be added in place of the factory "Y". The end of the "Y" typically gets cut out, and the new joiner welded or clamped in it's place. These are available from several vendors for the 4.0L, My car has the Pypes brand "X" (which I'm happy with). This part could also be fabricated by a competent custom shop doing the work.

A drivers side pipe will need to be aquired. I recommend getting a Ford pipe (they are available from aftermarket companies, but out of 3 aftermarket over axle pipes I've personally dealt with, all 3 were not bent correctly)

She'll also need to get the factory type hangers for the driver's side.

That's about it. It's not really terribly difficult to get done.

 

ive been getting ready to do this also and i remember someone putting up the part numbers for the hangers and drivers side pipe but i cant seem to find it anywere. does anyone know the numbers?
