Dinan Free Flow Axle-Back Exhaust - 2014-2024 MINI Cooper S | D660-0063-BLK

The Dinan Free Flow Axle-Back Exhaust (D660-0063-BLK) is a precision-engineered upgrade for the 2014-2024 MINI Cooper S (F55 5-Door), designed to optimize performance by improving exhaust flow and reducing back pressure. This system is built with 100% 16-gauge 304 stainless steel and features straight-through 2.5" tubing, resulting in a maximum performance gain of +4 HP and +4 LB-FT of torque at 5000 RPM.

Like all Dinan exhausts, this system is engineered to combat low-RPM drone, ensuring the cabin remains intimate while providing a great sporty sound that is pleasantly aggressive under hard acceleration. The design also achieves a 7 pound weight savings over stock and is finished with twin 90mm ceramic black tips, offered exclusively in black due to one tip being non-functional, which prevents non-matching discoloration.

Features:

• Verifiable Power Gains: Delivers a maximum performance gain of +4 HP and +4 LB-FT of torque at 5000 RPM.

• Optimized Flow: Features straight through 2.5" tubing for improved exhaust flow, increasing power and tone.
