M Performance Exhaust Getting quiter
I have a 18 M2 with DCT and the optional M performance exhaust. It works fine, flaps open and stay open, however it is quieter now after a year, and I expected the opposite it would get louder over time. Any suggestions to make it louder without a decat or voiding the warranty? Thanks

My suggestion would be a Fabspeed catted down pipe. Direct message Mike (vendor on this site) at x-ph.com for a great price and availability. Since you're concerned with retaining your factory warranty, you may want to consider the time necessary to swap back to the stock catalytic converter for any service you have done to your vehicle. That of course depends on your dealership/SA and tech. They may not even notice it's installed unless you have an issue with the vehicle and they look closer.
Are you sure it's quieter or have you just acclimated to the overall sound over time ? The sound is pretty subdued even with the valves open which is why we opted for the Fabspeed. --Monika Quote:

I have had my M2 with an MPE for about a year and no change in sound. I did get accustomed to it though, and whenever I need a little extra acoustics, I just press the "Traction" off button once when in Comfort mode and the burbles are much, much louder- does the trick for me

If you find yourself in an enclosed garage, get into 1st and lift off quickly at just under 3k rpm without shifting into 2nd. It can get pretty loud I must admit. |

This approach of intimidation and prepping BMW (by noting in within their system) to deny a future warranty claim is. Well. I'll leave it to your imagination how this sentence ends.
So hoping the hidden traction feature (totally forgot about that one) helps out. Kudos 'ND4SPD_M2'... Have a great one .. Quote:

Yes, I second this. Find a mod friendly dealer and have fun! This dealer documenting that you have an intake is pretty.....well...petty, to put it lightly.
