Description
Description
Dinan’s Free Flow exhaust system features 100% stainless steel construction measured to exact specifications to ensure proper fit via factory hangers and mounting points. Dyno tuned for maximum exhaust flow with minimum back pressure, this system is designed to provide a more aggressive sound under acceleration, while reducing drone inside the vehicle, thanks to computer controlled valves that limit noise during low speed driving and open fully during high-load conditions to allow free flow. The exhaust gasses exit through larger laser engraved polished or black ceramic quad tips.
Features:
- Max gain or +5 HP
- Uses the factory brackets and hangers for a factory-like fitment
- 3lb Weight Savings
- Dinan's Tuned Resonance Chamber Technology

- Operation of exhaust valve is unchanged so exhaust tone can be adjusted via the M-Drive settings
