DIY: F30 328i M Performance Exhaust (MPE)

CPT Smuggs · 01-12-2017, 12:17 AM

Replacing your stock exhaust with the BMW M Performance Exhaust is not hard to do. I took if very slow and careful, and it still only took 2 hours, start to finish. This could be done in as little as 30 minutes. The hardest part is getting the exhaust hangers off.

Tools:

Pipe cutter from Autozone (rent)
17MM socket
Small flatheat screwdriver
Pry bar or crow bar
WD40
Adjustable groove-lock pliers
Car ramps

Step 1: Raise the rear end with ramps (preferrably) or jack stands.

Step 2: Ensure that you have the correct parts before cutting!

Step 3: Locate the valve connection release, just above the tailpipes. Gently push in on the tab with a small screwdriver while slowly pulling down on the connector. Don't pull by the wires!

Step 4: Once off, tuck the connector above.

Step 5: Grab the pipe cutter you rented / purchased.

Step 6: Locate the factory dimple on the exhaust pipe just behind the rear axle. (red circle)

Step 7: Line up the pipe cutter with the dimple and slowly turn back and forth until the pipe is cut in half.

Note: Be sure the pipe cutter is 90 degrees to the pipe and not angled.

Step 8: Once the pipe is cut, spray the WD40 on the exhaust hangers and use the pliers + crowbar to pull off the existing muffler.

Step 9: Slide the clamp onto the exhaust pipe.

Step 10: Install the new muffler onto the hangers, position the tail pipes with your foot while tightening the clamp to hold the desired tail pipe position.

Step 11: Install the exhaust tips. (Not installed in picture)

I'll post some exhaust sounds next week. It's only been 1 day, so I don't have a strong opinion so far other than positive. The tone is a good deal louder than stock from outside the car, and just audible without being annoying from the inside. It has a "blurp" when upshifting and should develop a crackle on down shifts after a few hundred miles. So far, so good.

Well done!

I had the MPE installed on my 335... Noticed it gets quite a bit louder over the course of a month or so.

Coming from an Akarapovic on my E92 M3, its the perfect balance for me. Nice deep throaty sound at WOT, but quiet enough at idle to not piss off my neighbours / gf.

I love mine, I'm sure you'll love yours too!

VERY NICE! Thanks for the detail and following along to hear how these sounds after a few hundred miles.
