BMW M4 Performance Exhaust - AWE Tuning Track Edition Cat-Back (Diamond Black). A constant valve-open system for 2021-2027 M4 with quad 4.5-inch double-walled slash-cut tips.
The dual 3-inch layout and bespoke X-pipe use a straight-through path for flow and tone. AWE valve simulators keep the ECU happy, and inlet adapters mate to the factory mid-section; due to varying cut points, it isn't guaranteed to mate with other-brand mid-pipes. It's 50-state compliant. Note: this version is loud and cannot be returned due to sound preference.
Features
- Dual 3-inch cat-back with X-pipe
- Quad 4.5-inch Diamond Black tips
- Valve simulators included; No CEL, Perfect Fitment, and Lifetime Warranty
