Im not sure if its because it was installed incorrectly or if it makes that noise because of the fast DCT shifts.
Yes, this exhaust has a lot of character and shifts sound wonderful. You'd have more of a fart can sound with a leak. Check your fittings if it sounds off.

I have the race and paired it with a custom x-pipe....most who heard it at meets in Miami said its the best they had heard, and I have to agree haha. Definitely aggressive though, especially on cold start

I would be curious what people who own the exhaust can say about the sound at warm idle or cold start delete is like and also what it is like taking off early in the morning at low low rpm/speed
I just used SPL Meter on my iPhone to measure the sound volume during cold start and after cold start at idle:

- cold start: ~98 dB
- after cold start, idle: ~82 dB

I was standing about 4 feet from the back of the car pointing the phone mic at the exhaust.

So it's loud but not annoyingly loud to me. I can definitely hear it from within the house but the family or neighbors never complained (but I don't usually leave the house very early.)

For comparison sake my X5 xDrive50i with M perf package has a cold start volume of ~91 dB.

Yea took it to the shop for an oil change and they found a pretty significant leak between the connecting pipe and the muffler. I thought it sounded off based off how great everyone here said it sounded.

Now that its fixed, it is truly EPIC!!. Im glad it was 70 out today so I could drive with the windows down and listen to it.

Cool, glad that fixed it. Been there before, those clamps have to be right on. Hey, are you in NC? I used to live in SouthPark, nice city! Enjoy that balmy weather!

I think this is one of the loudest exhausts for the M3. what are you considering instead?
Not quite.... The Remus Race is louder and sounds better IMHO. It's also lighter and cheaper.

Yea it dramatically improved the sound. Was starting to sound like one of those coffee cans the guys put on civics.

The South Park area is pretty awesome, def the higher end side of Charlotte. Im a tad north in the Lake Norman area. Not many enthusiasts here, both the E9x's ive seen have been driven by trophy wives who prob never take it above 4k RPM.
