Where's the M Performance Exhaust Option? Or is stock good enough?
Ordering my M4 Competition X-Drive and I don't see an M Performance Exhaust option. It's also not in the ShopBMWUSA site. Both my F80 M3 and my M3 CS had the MPE and honestly, I didn't like how they sounded with the stock exhaust. So I have a few questions:
1) When will the G8X MPE be available? Can I get it later and will it include a carbon fiber diffuser for the center exhaust look? 2) Does the G8X stock exhaust sound as good as the F80 with an MPE? Might be a dumb question, but you never know. I'm guessing not since EU regulations are stricter. Does anyone have a video clip of both side by side? 3) Any good aftermarket titanium options? I am mainly looking for weight reduction AND sound, but I don't care about cat deletes. I want it to be legal.

The G8X MPE is already available, not sure how to order it in the USA but there's more info here:
https://www.bmw-m.com/en/topics/maga...bmw-m3-m4.html Crucially the big difference is the MPE exhaust layout is a bit different (centered quad exhaust) so it might not be to everyone's liking.

They also don't really sound any louder/better... though you do save a few kilos in weight. Hardly worth the ~$10k price (including lower rear valance update).

I kind of like how it's more unique. It's becoming more common for me to see factory vehicles with rear diffusers and dual exhausts (looking at you Toyota Camry & Corolla), so this looks a bit more 'performance' oriented (purely aesthetically).

Found this photo somewhere on Instagram, it doesnt look that bad. I might actually consider it once I hear more of it.

I personally love the look, to each his own, but not for a $10k price-tag. I got the performance exhaust on my 2016 I think it was less than half the price. Seems excessive.

Still, it doesn't seem worth it given the overall quality of the last MPE. I've had to replace both of mine for various reasons, all under warranty, but still.

The F80 MPE was a big improvement over stock. Is this one not because of new EU regulations?

Before (stock) (go to 0:35) After (MPE) (go to 6:46): IMHO, the improvement in sound is pretty minor... likely because the cats and resonators/filters are still in place.

I like it. Hence my avatar. I also heard it was going to be $10K, but which option is this for? Im hearing there is going to be a cut up design, axle back, like this, and there will also be a full replacement system.
For future reference, I've done all of the legwork in collecting the part numbers for the system. Prices aren't as bad as they seem. It looks like there are a few companies that list the exhaust in US dollars, and the center exit is just over $5,100. The rear diffuser, about $1,700, and the tailpipe and bracket kit is about $1,200. If you factor in a decent discount, you can probably have the entire system, for about $7,500. Rear Diffuser Center Exit: 51-19-5-A19-8B5 Center Exit Tailpipe and Bracket Kit: 18-30-5-A23-286 Center Exit Exhaust: 18-30-5-A23-283

Hard pass…for under 5k you can get something more “M heritage” instead of this Lexus LFA thing that will probably won’t sound much different or loud than an aftermarket.
