Precision Fitment & CNC Machined Flanges
Engineered for a direct bolt-on installation with perfect alignment and sealing—no cutting or welding required. Retains factory O2 sensor locations. -
Enhanced Exhaust Sound
Deepens and sharpens the AMG V8 note, delivering a more aggressive tone under acceleration and satisfying turbo spool sounds. -
Dyno-Proven Gains
Gains of +20–30 HP on stock tune, and significantly more with ECU remapping or tuning software. -
