435 xdrive Exhaust
Just bought a 2016 435 coupe with 15,000 miles. I want to improve the exhaust sound and don't want any drone. Any input on the Borla Atak system? I've heard good sound from just a Rev9 axle back but have a feeling it probably drones. Any input is appreciated!

The MPE is pretty decent without being too loud. It comes with the exhaust valve as part of the exhaust. You can get the chrome or carbon Fiber Tips. I had it on my 2014 335i and no drone but Wife thought it was too loud in the morning start up. The other is the Dinan which I have heard and it is a deep growl. Both of the above are axle back so they retain the mid-pipe muffler. These can be found used on the classified section, good luck!

If you are concerned about drone, my 2 cents worth:
1) Leave the midpipe resonator in (just get an axle back). 2) Get an exhaust with the left flap in, or get the flap welded into your new exhaust. I did that to my Active Autowerke since I found it way too loud during light throttle acceleration. |

I installed a M2 muffler on my 435 xdrive and love it. using my JB4 I can control the exhaust valve to operate like the stock setup or open all the time. it sounds so much better than the stock muffler and looks great with the quad tips.

I'm extremely happy with the sound/tone of the Active Autowerke. It coupled with the ER catted DP has a really nice growl when you ask for it, quiet during cruise. |

I think downpipe should be your first option; personally I'd just go catless since it seems like no CEL is ever guaranteed.. Then I'd go with a valved rear muffler such as Valvetronic; it allows you to be pretty much straight piped when open and then super quiet when closed. I even deleted my resonator and it still sounds pretty damn quiet when closed.

Ahhh.. ok, then you just have to cut it off and replace it with another axle back.
Others have cut out the mid-pipe resonator (adds drone), or replaced the down pipe. The DP will make is sound better, but the axle back is the best way to get the aggressive sound. I was in the same boat as you and didn't want it insanely loud. With the Active Autowerke it was brutal until I put the exhaust valve back in the left tip. When the rear doors were open, the cold start was deafening in the cabin. Now, its really quiet until you go to sport mode and make it work. I really like it now, but I was regretting life choices prior to putting that valve in. Nice thing about the Active Autowerke is the left tip is a stainless elbow that you need to clamp in the hole. If you are DIY, and don't have a welder, its easy to take that to a shop and have them weld in the old OEM valve. |

I have to charge my gopro, can post an updated video by the weekend. Will upload the morning cold start video tomorrow, with some mild revving
Edit: The price I mentioned earlier does not include the tips, they are probably $100-150 for the new chrome ones, CF tips are around $500. I'd look in the classified section or get aftermarket tips which probably look better than the chrome OEM tips. In case you end up getting the MPE.
