BMW X7 M60i & Alpina XB7 Valved Cat-Back Exhaust System

2.75″ T304 Stainless Steel Exhaust with Electronic Valve Control

Overview

The BMW X7 M60i and Alpina XB7 deliver immense performance and luxury—but their factory exhaust holds back the soundtrack these SUVs deserve. The Valvetronic Designs Valved Cat-Back transforms the experience with a more raw, motorsport-inspired tone, sharper gearshift snaps, and an enhanced character throughout the rev range.

Connecting to OEM or aftermarket free-flow downpipes, this 2.75-inch system runs unrestricted from inlet to tip. In testing, we found that an unresonated design delivered the most engaging sound, producing pronounced pops and crackles when shifting, while maintaining a drone-free cabin with the valves closed.

The included electronic valve controller allows you to fully control the exhaust at any RPM, unlocking maximum enjoyment whether you’re cruising in comfort or pushing the M50i powertrain to its limits.
