Alright, so I went on a drive to Palomar this weekend---anyone who lives in SoCal should make this their very next drive, it's phenomenal. One of the other Z4Ms there had an RPI exhaust. I asked him about the drone, he said he installed some sound proof padding in the boot (it was a coupe), and that seemed to help a lot in his opinion. I drove it and yeah, the drone wasn't too bad, but it was noticeable. I might go that route though: RPI, sound proof padding, plus a J-pipe? He recommend that as well, and some others I've seen also mention some "custom baffling" that reduces the drone but keeps the bark.
here's a link to the guy with the baffles: Any thoughts on how feasible this is? Or am I just getting into a potential headache? |

I just installed the sound proofing material this weekend. Will let you know in the coming week if it made a difference.

After installing the headers I find that the drone has increased and on longer trips it can be a bit much, especially when you have a passenger.

^Yep. Still love my RE cans.
Drone? Bah! But I'll grant you it probably sounds different in a coupe than a roadster.

haha well the idea is to have a great exhaust note when accelerating or revving, not a constant drone that makes it impossible to carry on a conversation with a passenger on road trips or drives around town. This is my DD, it has to be livable and fun.

On my coupe, I ran SS headers with aftermarket exhaust and the drone was too much. I tried sound deadening materials in same spots and it barely made a difference. End of day only thing that made a real difference was swapping out the hardware for different combination of resonators and mufflers.

Some pics with custom J-pipes (aka Helmholtz chambers/resonators):

I have Eisenmann cans on my M. Very nice sound, grown up noise if you will. I was going to do Eisenmann on my 3.0si too if I hadn't sold it.

3.0si has very limited options. If you’re not going to bother with headers, I would go custom using some high quality parts. You’ll save a lot and get same if not better sound and performance.

QFT. A nice Magnaflow universal dual-tip muffler with a well-built custom headers-back system will sound great and will also be inexpensive to have built on the car. Check Yelp for the most reputable exhaust shop near to you and go talk to them.
