Unlike our previous full catback design, this updated version is more cost-effective, easier to install, and focuses only on the section of the exhaust that actually changes sound and driving experience.\u003c\/p\u003e\n\u003cp\u003eOn the M340i and M440i platform, a full catback simply is not needed. The factory midpipe is already a straight-through, non-restrictive design with no cats or resonators, meaning there is little to no performance or sound benefit from replacing it.\u003c\/p\u003e\n\u003cp\u003eThis axle back system provides a deeper, more aggressive tone under throttle while remaining refined and comfortable during normal driving. It also upgrades the factory single-valve setup into a true dual M-style valve configuration using the OEM valve motor along with an additional included valve and harness. The exhaust continues to function perfectly with OEM drive modes, staying quiet in Comfort and fully opening in Sport.\u003c\/p\u003e\n\u003cp\u003eInstallation is quick and straightforward using OEM BMW designated cut points, allowing the car to easily be returned to stock later using OEM BMW sleeve clamps.
