Drop 10 lbs and replace your midpipes/resonator for a free flowing X-Pipe to get a smoother sound and decreased back pressure!

An X-Pipe can do wonders for your engine for performance and sound. Exhaust gasses come out of your motor in pulses from each individual cylinder, with a cross-over or x-pipe the exhaust gasses meet in the middle and combine. The result of the combining gasses is a smoother path leading to lower amounts of back pressure, a more free-flowing exhaust and leads to increase power and response. Combine with a new rear muffler for best results!

BMW's straight six motors have been referred to as sounding like chain-saws, and being "raspy" or "metallic". Transform your exhaust with our mid section exhaust with an integrated x-pipe to smooth out your exhaust tone and enjoy the sound of your M54! The mid section x-pipe comes with new hardware for connection to the downpipes and includes superior exhaust sleeves to slide over your factory rear section.

Upgrade your BMW E46 exhaust system with the Turner Motorsport X-Pipe, ditch the bulky factory midpipes and resonator, reduce backpressure, and let your engine breathe the way it should. This free-flowing X-pipe delivers smoother exhaust tone, improved throttle response, and a noticeable performance advantage over restrictive OEM components. Factory exhaust pulses exit each cylinder separately, creating turbulence, rasp, and unwanted backpressure. A performance X-pipe merges and balances these pulses, producing a cleaner, deeper exhaust note while increasing overall exhaust efficiency. For the best sound and power gains, pair the Turner X-Pipe with a high-flow performance rear muffler. BMW’s straight-six engines, especially in the E46 323i and 328i, are known for their metallic “rasp” under load. Turner’s mid-section with an integrated X-pipe dramatically smooths the exhaust character, enhancing tone without sacrificing flow. Each system includes upgraded hardware for the downpipe connections and premium stainless steel exhaust sleeves for a perfect, leak-free fit to your factory rear section.
