Xforce BMW G80 M3 G82 M4 Varex Cat Back System

Unleash the full potential of your BMW G80 M3 or G82 M4 with the VAREX dual 3" cat-back exhaust system, expertly crafted from premium 304 stainless steel. This performance-driven system is engineered to enhance both the sound and appearance of your M-series vehicle. Featuring dual VAREX valved mufflers, it allows you to tailor the exhaust note to your preference—go from aggressive, track-ready tones to a more refined, quiet drive with the push of a button. Designed for twin-turbo S58 engines, this system is the ideal upgrade for enthusiasts seeking both dynamic sound control and premium build quality.

With mandrel-bent tubing, V-Band flanged connections for easy installation, and quad 4" polished double-wall tips, the system offers a seamless blend of performance, style, and functionality. The dual 2.75” OEM inlet transitions smoothly into dual 3” pipework, flowing into a single East-West mounted muffler that houses the dual VAREX valves. Whether you're carving corners or cruising the highway, the VAREX cat-back system transforms your driving experience. Please note: vehicles equipped with OPF/GPF will require an OPF delete kit for proper installation. This system is a direct bolt-on fit and comes with everything needed for installation—no cutting or welding required.
