The Artek Motorsport midpipe for the BMW G80 M3 and G82 M4 is a direct replacement for the restrictive factory secondary catalytic converters and resonators. Constructed from high-grade stainless steel, it features smooth mandrel bends to optimise exhaust flow. The use of an X-pipe balances the tone perfectly without affecting power

By reducing back pressure and improving engine breathing, the midpipe delivers noticeable gains in throttle response and power output. It also transforms the exhaust note, delivering a deeper, more aggressive sound while retaining full control of the OEM exhaust valves for a quieter ride when desired.
