New Mods - Boss Diffuser, Boss H-pipe & Axle-back
I was very busy today modding the new stang. I added an OE Boss Rear Diffuser, FRPP Boss H-pipe with side pipes, and Magnaflow Street Series Axle-Back. The new exhaust sounds amazing! Below are notes and photos of everything done.
Before rear view
Rear wheels, tail lights and rear bumper cover removed
Trimming off portion of bumper cover. There are lines inside the cover showing where to cut :thumbsup:
First drill where slots need to be cut - two slots at each exhaust outlet
Cut remainder of slot with coping saw
Trimming/Cutting all done
Diffuser installed on bumper cover
All tabs snapped into place, plus 6 white clips pressed into place
One exhaust outlet showing where two tabs snap into freshly cut slots
Completed look
Original h-pipe
New Boss h-pipe with side pipes (restrictor plates removed)

What was the part number for the rear diffuser? I've seen two different numbers DR3Z-17F828-AA and DR3Z-17F828-BA. The second one is listed on ford accessories and says no drlling/cutting required. My only guess is the first one is the replacement part for the Boss/Cali Special while the second one is a retrofit kit. Can anyone confirm that?

Looks awesome. Kinda now wish I hadn't been so impatient when I got mine and installed it. basically i cut off the tabs around the tips and got a little creative. at some point I'll probably try to get another boss diffuser and do it the right way.

Thanks!
I'm sure no one has noticed your missing or broken tabs, lol. But it would bother me too! Thanks!

Boss great job on the install and pics. I will be installing the same diffuser as well as soon as my car arrives. Didn't expect so much cutting was required. Is the bumper cover marked inside where to remove material?

Also, below are photos of the only extra hardware you should need for the install.
A speed nut and screw like pictured for each exhaust outlet. I could never locate the part numbers for these. However, my local Ford Parts Dept. had these on hand that worked perfect.
Six of these small white clips for securing the tabs across the center area that aren't self-securing.
Two of these clips for the bottom center support, as you can't remove the original ones without destroying them.

I'll be sure to tell my wife that doing all the cutting and bringing the bumper cover into the family room
is just part of doing things properly.
I haven't told her yet about having to cut anything on my new $40 k car.
Lol
