DIY RPI Exhaust Using Jack Stands

DIY Intro:
50 Photos / 17steps / Post #1 Part I / Post #2 Part II / Post #3 Part III
Since I have removed and installed the axle back exhaust about a dozen times, I figured it was time to do a DIY. This is photo heavy step by step DIY including some good tips. The DIY only includes instruction for the passenger side. The steps are exactly the same for the driver’s side. You may also notice that the RPI's are already on the car while it is being jacked up. For the purpose of the
DIY, I put the passenger side OEM muffler back on after the car was off the ground.



Hand Tools Used:
01. 3/8 ratchet
02. 3/8 13mm deep
03. 3/8 12mm shallow
04. 3/8 8mm deep
05. 3/8 8mm shallow
06. 3/8 2" extension
07. 3/8 4" extension
08. 1/4 ratchet
09. 1/4 13mm shallow
10. 1/4 8mm shallow
11. 1/4 3" extension
12. 13mm ratcheting combo wrench
13. Cordless 90 degree driver with 3/8 male adaptor
14. Graduated caliper

^chris, thanks for the superb pictorial writeup! i opted to go the lift route (a lot faster and convenient) and have since re-adjusted my exhaust tips since my initial install. what really helps is ur very last tip on exhaust tip protrusion. my left tips stick out ever so slightly more than my right ones, so i'm going to readjust the 8mm nuts just immediately below the rear bumper cover to fix this. however, i do notice my tips still stick out quite a fair bit more than urs do? it's protruding about 0.5 inches now.

this whole perfect placement thing is seriously a work of extensive patience and meticulous detail. i've opted to go visually with my alignment since i don't have access to a digital micrometer, but i'd say it's about perfect for my very particular human eye now.

Awesome thread right here! Could of used this the first time I did a swap. After six or seven I'm an old pro. Had no idea about the moving rear cover though. Sweet!

Very awesome of you to do this writeup. The fact that you took the time to explain how to jack the car up properly is golden. This will be very useful when I change out my diff and tranny fluids.

Thanks again!

Didn't know about the 3/8" play in the bumper. Will need to see if I can get my exhaust protrusion to look right with your tip. Thanks!

A lift make things much too easy
Glad you found the write-up useful because that's what it's all about. Since gasket ring is round and the mufflers pivot on an axis, the lower the muffler hangs the further it protrudes from the bumber cover. If your muffler hang a little lower than mine, this may be why thye stick out further

no problem, this is why included "using jack stands" in the title. I figure if someone is searching the DIY for how to Jack up the Z4, this thread should pop up. I'm glad you found it useful.

Yep, it can be done without rear diffuser removal. You just get better access around the bulky stock muffler with it romoved.
