New E46 323/328 Resonator Delete

Ditch the bulky mid-pipes and resonator, cut backpressure, and let your engine breathe! Unlock smoother sound and better performance with a Turner X-Pipe.

Factory exhaust pulses exit each cylinder individually, creating turbulence and backpressure. An X-pipe merges those pulses into a single, balanced flow, reducing restriction, improving response, and delivering a cleaner, more refined exhaust note. Pair it with a performance rear muffler for maximum gains.

BMWs straight-six engines are known for their trademark rasp and metallic tone. Turner's mid-section with an integrated X-pipe transforms that character, smoothing out the harshness and letting your M54 sound its best. Each kit includes fresh hardware for the downpipe connections and high-quality exhaust sleeves for a perfect fit to your factory rear section.
