DIY: M Performance exhaust

So the first "major" mod I performed on the new M2 is the M Performance exhaust. Disclaimer......no way in hell I did it in 2 hrs like the paperwork says. I now see why the port puts out so many hack jobs.....

The skid.....yes a skid arrived undamaged from Sun Motorcars. I once again must mention.......Brian is the man for BMW parts hands down. The packaged arrived to him, he opened and inspected it to verify it was un-damaged the latest revision then added additional packaging to protect it then shipped it to me. Plus the pricing is unbeatable. Above an beyond period. He never fails to give impeccable service

It took me all day in the 37 deg temps to wire & install but I am very particular about stuff like routing cables evenly, shaping of heat shielding, sealing around plugs, etc. Plus I always measure twice, cut once. I also do it on my back like a hooker...... no lift

I put the car to sleep before installing the BT module and harness so did not unplug the battery terminal. Ran everything close to what the docs said but revised it to my liking. I struggled a bit with getting the pin in the one connector under the fuse block but finally got it after taking the connector out. The other wire already came with a connector attached. Took all the shielding out to run wires behind and installed the old flap dummy plug then stowed it up behind the cover exactly as the docs tell you.

I used a pipe cutter at the dimple marked location so the cut was straight..... fuck this piping is super thick, took a bit of work. Then I hit tooled the edges so the interface was nice and smooth.

Not an easy DIY for me but I hope since I did....there will not be some of the issues others had.

I saved the tips from the old M4 and re-used these to save money so I only had to buy the exhaust.

All and all the fit is almost spot on, might have to tinker with it slightly but really no complaints. I will update the post after i drive it and take a couple of daylight pics.....I have my break in service today

Love it when people do DIY themselves. I hardly see this on BMW's forums. Good job!

Very nice job! I would recommend turning off the ASD. Open valves + fake cabin noise was a bit too much for me.
Also, the side by side picture of OEM with MPE shows the latter is pretty much a straight pipe setup from BMW

If you mean the stock tips I think they are a different diameter, so no. There are a few aftermarket tips that will fit the MPE that are much cheaper. See sponsor classified section.

No DP at this early stage, only 1300 mi and that would be an instant warranty flag

Good job man nice DIY! Not sure if you had jackstands on the front, but you shouldn’t rely on floor jacks to hold the car up (should only be used to raise the car). Stay safe! I have the same ///M flag on my garage wall too

Yes not the safest way but best thing in place of a lift...... I don't like siting the alum suspension components on jack stands. I did the whole M4 this way..... I take it carefully and check the jacks often.....

Thanks guys! This exhaust rocks and the BT communication has been consistent so far, has stayed open as far as i can tell. There is highway drone when flaps are open (i have asd off) but I don't really care. I have noticed the M2 transmits more exhaust vibration thru the chassis than the M4 did.... much more with the MPE but it has bark

there is a whole dummy plug/routing doc:

As for cutting, who knows why they design it that way. Maybe for ease & speed of install at the port? Who knows.......
