MAD BMW X3M X4M F97 F98 Axle Back Exhaust
The MAD X3M/X4M Axle-Back brings real exhaust character to BMW's performance SUVs. It pairs flexibility with a sportier, louder note and a clean, aggressive look at the rear.
Features
- Pairs with the MAD Single Midpipe (no cutting) or your factory midpipe (cutting required).
- Maximum gains of +5 HP and +5 lb-ft.
- Pleasingly louder, sportier tone with drone-abatement to keep cabin resonance down.
- 4.1-inch (101mm) tips.
- Reuses the stock valve actuators with unchanged operation — adjust the tone through the M-drive settings. The computer-controlled valves limit noise at low speed and open fully under load.
- 100% 304 stainless steel construction with factory-like fitment and included mounting hardware.
Fitment
