The Active Autowerke Valved Rear Axle-Back Exhaust is designed specifically for the BMW X3M and X4M (F97/F98). It addresses the stock exhaust's subdued sound by providing a deeper, more aggressive tone while retaining stock valve functionality.

  • Made in the USA from 304 stainless steel
  • Engineered to increase sound level and optimize exhaust flow
  • Utilizes factory valve actuators for controlled exhaust tone
  • Test-fit on F97/F98 exhaust fixtures for guaranteed fitment
  • Complete with all necessary installation hardware
  • Fits all F97/F98 BMW X3M and X4M models

This axle-back exhaust pairs best with Active Autowerke mid-pipe and catted downpipes for a full system upgrade, delivering an authentic M-car exhaust note. Replacing only the rear section provides a subtle sound improvement, with the most dramatic enhancement achieved by also upgrading the mid-pipe.

slightly smaller than sky high
Size: 30 FT, Style: 0 (1/0) AWG RED
wire is okay but it is definitely on the thinner side, was slightly smaller than my sky high 1/0 wire but for the price difference this is definitely worth it
