With an awkward grin on his face he said "how much did you pay for that?!?!" I've worked with him for years.

A little back ground. I'm 43 and coming from a 2017 f80 competition pack with the OEM "sport" exhaust, which is at least 20 times louder (maybe more) than this m-performance exhaust. The M3 sounds like a monster inside the cabin (active sound deleted) next to my F36. The funny thing is, the majority of the F80 guys don't think the comp pack exhaust is loud enough. I don't understand how BMW can call this a "performance" exhaust then you have to drive with the windows down below 30 and at WOT to hear it!!! And yes I did watch videos and thought it sounded okay in the drive away shots. Maybe I just got used to the noise of the M3, because I remember being impressed by the MPE I had on my f30 328. And I also remember thinking "woah, how can that be street legal" when I first heard the sales manager start up my M3 on the showroom floor.

So now, the question is, how can I make it louder (no drone) to where I can actually hear it with the windows up? MPPK (only louder crackles?)? Resonator straight pipe? Catted DP? Will the catted DP pass emission check in MA?

I don't want to give up on it just yet.

Thank you all.
If you want it louder do a resonator delete and add a DP. Fabspeed catted DP guarantees no CEL.
So with this down pipe, no need for a tune?

Will it pass the smog check in CA?
