Dinan Free Flow Axle-Back Exhaust - 2016-2018 BMW M2 | D660-0056-BLK

The Dinan Free Flow Axle-Back Exhaust (D660-0056-BLK) is a 'Jekyll and Hyde' exhaust system for the 2016-2018 BMW M2, engineered to deliver the aggressiveness of a track exhaust and the refinement expected of a daily driver. This system achieves this duality by utilizing the factory exhaust valve in concert with Dinan's muffler design.

Dyno tuned for maximum exhaust flow with minimum backpressure, this system provides a maximum gain of +6 HP and +5 LB-FT of torque. The core of the system is a computer-controlled valve that limits noise during low-speed driving. For maximum enjoyment and sound, the valve opens fully during high-load conditions, allowing the exhaust to become a straight pipe through 3.25" tubing to achieve peak power, flow, and tone. The exhaust is finished with Dinan's signature enlarged, laser engraved, black ceramic quad tips.

Features:

• Verifiable Power Gains: Delivers a maximum gain of +6 HP and +5 LB-FT of torque.

• Acoustic Duality: Utilizes the factory computer-controlled valve for adjustable sound: quiet and civilized when closed, and a straight-pipe tone when open.

• Flow Optimization: When the valve is open, exhaust flows straight through 3.25" tubing for peak power and tone. The stock exhaust valve actuators are reused.

• Superior Material & Construction: Built from 100% 304 stainless steel construction to resist corrosion.

• Aesthetic Excellence: Features quad 3.5" laser engraved black ceramic tips with the Dinan logo for an aggressive look.

• Fitment Integrity: Designed to use the factory brackets and hangers for a guaranteed, factory-like fitment.
