The ultimate future-proof midpipe upgrade for the S58 engine platform. The IRL FMU V2 features an innovative modular construction that allows you to easily switch between a full high-velocity straight-pipe note and a smoother, deeper resonated profile as your build progresses. By optimizing exhaust gas scavenge intervals, it aggressively bumps up throttle response and mid-range performance while completely redesigning the sound spectrum to kill low-end rasp. Engineered from high-strength stainless steel for flawless clearance around factory chassis braces.
