• Deeper, More Aggressive Sound: Say goodbye to the muted factory exhaust and hello to a thrilling growl that turns heads.
• Premium 3.5" Diameter: Optimized for maximum airflow and performance gains.
• Stepped Brace with Laser-Cut Logo: Our unique brace design not only ensures a perfect fit but adds a touch of personalized style to your undercarriage.
• Easy Installation: Designed for hassle-free bolt-on installation (professional installation recommended).
• Valve Controller: Valves can be routed to be opened or closed with your factory M Buttons or use our controller to open valves all the way up. NOTE: The factory buttons do not fully open up your valves when revving the car while on Park, or when driving at lower rpms. If you want to fully open your exhaust its best to use our remote which will fully open up your valves and allow for maximum sound when you want it.
