Just installed a set of Speed Engineering headers and 3" X-pipe system on my son's 2022 GT w/PP1. Like any header installation on an S550 Mustang, be patient and swear often. Remove all the customary obstacles and lower OEM exhaust manifold mounting studs etc. and have at it. (Having a lift is such a valuable luxury I could never do these installations on my back anymore.) For such cheap headers, I'm pleasantly surprised by how well they fit and how each header pipe is a continuous length of tubing without splices. Weld quality is as good as it gets. Feel free to PM me with any questions, I'll be glad to assist. Main concerns to address:
Driver's side: 1.) Slice off the top of the motor mount stud, it will interfere with one of the pipes.
2.) smash a flat into the same curved pipe that hugs the left frame rail if you want additional room than the almost line-to-line clearance.
Passenger side: 1.) The A/C compressor location is a major challenge to overcome and there's no way I'm removing it the way Ford's Service Manual recommends just to remove the OEM Manifold. Pound a flat into the header pipe to facilitate installation against the compressor. Also note, removing that lower mounting stud requires an E8 ratchet wrench to just barely have enough room to remove it.
2.) The A/C hard line mounting clamp on the frame rail has a "tail" that intrudes into one of the header pipes running against the frame so slice off the excess material.
I used OEM Gaskets, studs and nuts and I'm just waiting on Secondary O2 spacers before test firing. I suspect, the noise will attract some unwanted attention.
