ARMYTRIX Valvetronic Exhaust System (OPF/Non-OPF) | BMW G82 M4 2021+

INCLUDES: OPF-Delete Front Pipes + Resonated Mid Pipe + Mid Pipe 2 + Valvetronic Muffler + Quad Chrome Silver Tips

Armytrix is dedicated to bringing the finest BMW G82 M4 Valvetronic exhaust upgrade to the aftermarket scene. We subtracted the unnecessary weight from the stock system. The attention to detail can be readily witnessed on the masterfully welded connections. Heavily engineered from the front all the way to the rear exits, this system functions as a single-minded unit; to boost the vehicle€„¢s power and sound. The smoothness of the flow generates considerable horsepower and torque gains without suffering much from backpressure. Amplification of ferocious sounds across the rev range provides new stimulation to the auditory system.

When the lights dim, the spotlight hits, all eyes are on you, feel the rush of adrenaline, the surge of exhaust audio overwhelms the airwave. The free-flowing nature of our exhaust offers an escape route for the most primal sound to emerge directly from the engine. A deep timbre defines the lower revs, a hypnotic purr, the prelude for the incoming devastation. Full throttle engaged, an immediate F1 style audio pitch invades and occupies your auditory system; drowning out the thoughts of doubts and disbelief. Convert non-believers into fanatics, the journey has just begun.

Note: The exhaust system is integrated with OE valve control.


  • Ultimate beast performance to receive as it has been tested multiples times and verified with the highest standard wind tunnel test.
  •  More engine performance as the downpipe is equipped with cutting-edge flexible pipe technology that facilitates cooling and protects exhaust from breakage.
  • Rapid cooling ceramic coating reduces underhood temperature and rust resistance.
  • High standard T.I.G hand welding
