Armytrix is dedicated to bring the finest BMW 4-Series 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 back pressure. 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.

Amplified performance, enhanced versatility, optimized efficiency; everything we offer serves the sole purpose of tuning your vehicle to become “combat-ready” for the ever changing streets. Precisely designed and masterfully crafted, we bring the revolution to the home front.

Meticulous and calculated, the designing and manufacturing processes for each system were conducted under strict protocols and to the highest of standards. The fabrication process is handled by master craftsmen and their battle-hardened skills are readily demonstrated on all titanium and stainless steel exhausts. The quality of the TIG welds on the notoriously difficult titanium is simply stunning. We promise a well-made, versatile, performance oriented exhaust system that checks every box on your checklist.

Rapidly changing circumstances require a countermeasure that can keep up with the increasing pace. Our valve system is built to offer tremendous functionality to the user’s daily drive. No longer does one have to pick between explosive exhaust audio or playing-it-safe stock settings. The smartphone app allows for unprecedented access to real-time events and backs it all up through precise data logs, with everything displayed on user friendly interfaces. Adding to the repertoire, the digitized controller creates yet another method for one to gain access to the valvetronic system.
