ACM Modded exhaust for an E92/E93 M3. ACM charges $400 to mod it and they keep your old exhaust. Won't fit an E90 M3. You get 90% of the sound of a Meisterschaft gt2 without the drone (owed both). Selling due to I will be going catless and putting back stock exhaust. Sample clip of how it sounds. (Not my car)

Is this just with the 2 perforated pipes replaced with solid pipes? I'm seriously considering selling my Dinan and going with this setup.

Uploaded photos. This completely bypasses the center section of exhaust. Almost like a straight through exhaust but without the drone since the helmholtz chamber is still in place.

I've tried 3 aftermarkets and ended up back with this one. Absolutely no drone even with test pipes. Well worth it.

Might be a dumb question.. but thinking about going this route and selling my Dinan exhaust. What's the difference in the 2 pipe and 4 pipe mod. Which does ACM do? What's the better sound?

Sound being better is subjective honestly lol. The 2 and 4 pipe methods only applies to center pipes. The ACM Mod bypasses complete center of exhaust meaning th entire center is useless and goes straight out. But you still keep the helmholz chamber. You get Zero drone with ACM Mod and it's the loudest. So for you since you have dinan the 2 and 4 pipes method will be a downgrade in terms of loudness. ACM Mod will be as loud if not louder and whether or sounds better or not is your choice. You get Zero drone.

Thanks for the explanation!! Yeah, better is certainly subjective. I like the Dinan but wish it had a little deeper growl if that makes sense. I have the Dinan x pipe too, but hate it being catless, so thinking of changing the entire setup, going for a catted x pipe and thinking about the ACM mod. Don't really want it to be any quieter though, but prefer cats because of the really rich exhaust.

shipping would be like $150-$250. Depending on where so it's really not worth it and i doubt anyone would pay that much for shipping.
