FREEFLOW EXHAUST; G8X M3/M4; BLACK

The Dinan Valved Axle-Back Exhaust for the G8x M3/M4 significantly improves upon the stock exhaust by providing a deeper, sportier sound and additional amplification. It features enlarged 76mm (vs 70mm stock) T304 stainless steel tubing, which is TIG welded and brush finished for optimal appearance and durability. The system intelligently retains the factory exhaust valves, allowing for a refined driving experience; flow is directed into the muffler for a subdued sound at low speeds, and intelligently bypasses the muffler for a near straight-pipe design and maximum aural enjoyment under high-load conditions. Visually, the exhaust is completed with massive, quad 4.5-inch (114mm) clamp-on, double-walled, black ceramic coated tips, each laser engraved with the Dinan logo, seamlessly filling the factory cut-outs for an OEM+ aesthetic with a healthy dose of audible attitude.
