2023 BMW XM 4.4L Twinpower Turbo V8 w/ X-Pipe & Borla ATAK!
#exhaustaddicts #bmwxm #borlaatak
The BMW XM is already a polarizing beast, but we’ve officially given it the voice it deserves. In this video, we take the 2023 BMW XM (G09) and its 4.4L S68 Twin-Turbo V8 to the next level with a custom X-Pipe and a Borla ATAK exhaust system.
The factory exhaust on the XM is notoriously quiet for a vehicle with over 640hp. By adding a high-flow X-Pipe to smooth out the exhaust pulses and Borla’s most aggressive ATAK (Acoustically-Tuned Applied Kinetics) mufflers, we’ve transformed this hybrid SUV into a fire-breathing monster.
Watch as we cover:
Cold Start: Hear that S68 V8 roar to life.
Exterior Walkaround: A look at the aggressive quad-stacked exhaust tips.
Rev Test: High-RPM screams and aggressive downshift burbles.
Drive-By: Wide-open throttle (WOT) pulls to hear the ATAK technology in action.
Whether you love or hate the XM's styling, you can't deny this sound. Is this the best-sounding BMW XM in the world? Let us know in the comments!
