AA + MPE DYS on m440gc

totalone · 06-18-2023, 10:12 PM

So was able to replace my stock exhaust with MPE. Was fairly straight forward. Sounds really nice. I really like it, it is just loud enough for me and in eco pro mode just like regular eco pro mode on stock exhaust.
Overall it sounds awesome with AA downpipe. Its jsut loud enough for me and in quite mode its just like stock.

1. Remove exhaust tips, they will get in the way of you pulling out stock muffler. (GC has rear braces across the car unless m340). Use number 10 socket (there are 4 bolts all together one of each side)

2. Cut the pipe at the nipple. Make sure you measure it just in case. I measured length of pipes on MPE to see where the cut will happen. Remember accommodate for extra 1 to 1.5 inch for the insertion. I used these to cut the pipe

3. Unbolt rear stability bars so that you can drop stock muffler lower in order to pull it out from the rear. You will need T60 and number 13 socket. T bolts are located on steel bulk near muffler, 13 bolts are located near each rear tire.

4. Unbolt rubber support hangers. 3 of them. Two at the muffler and one on the passenger side near rear diff. Socket number 13.

5. At this point exhaust will drop. Slightly pull on brace that was unscrewed in step 3 and pull exhaust out from the rear.

6. Place clamps on the pipe you just cut. (The one that still attached to the car)

7. Pull exhaust onto the pipe. Remove rubber supporting hangers and place them in same spots on the MPE (https://www.amazon.com/dp/B0012S9A5U...roduct_details). MPE will have a small windows on the tips that you will slide onto pipe in order for you to see it how far its inserted. Pull it all the way until those windows are covers.

8. Place back rear stability bars so that your exhaust can just hang on it, so you can easily work with it.

9. Place rest of the pieces together. from previous steps

Thanks for posting this! I have a 2022 M4401 GC as well and I'm about to pull the trigger on the MPE.

JMJ2323 · 09-29-2023, 11:47 AM

Well, got it installed but not an easy process without a lift and by myself. A couple of tips from my side. It probably would have been good to have 2 pipe cutters. The first pipe was way easier than the second and these tools seemed to be good for one pipe. Both were hard as hell to cut through the top so I need a mini hacksaw to finish them off and a lot of swearing. Also, the rear two Torx 60 bolts were on so tight I thought I was going to break the bit. I needed a 3 foot breaker bar to get them started. The sound is amazing and in the end worth the effort.

Very nice post. How are you liking it in the long term? Any sound clips?

yeah I have clips. If you add AA and MPE its just loud enough for me. I would not want anything more louder.

I have videos somewhere before and after MPE. If I dig around I can probably find stock, AA and stock axle back, and AA with MPE

I have stock videos and video with AA and stock axle back but there is my license plate did not want to upload that.
Note it will get little louder over time. This is right when I just installed it. Right now it got slightly louder
