I've watched some of the videos, but have also heard the M Performance Exhaust doesn't sound as good on recording as in person.

I'd be curious for anyone that has installed one if they found it to be a worthwhile modification. Does it provide any noteworthy performance gain?

Also, are there any good deals on them at the moment? Lowest I've found is $2179 on BMW Parts Now or $2194 on GetBMWParts. Any opinions on the vendors?

I presume they should be shipping the current revision of the design at this point. I love the way the car sounds now, but it is somewhat subtle with the OEM setup, especially when compared to our 340 MPPSK.

Thanks for any insight you might have!
