Dinan Free Flow Axle-Back Exhaust System with Black Tips for BMW M2 ( F87) 2016-2018
Dinan's Free Flow Axle-Back Exhaust System for the BMW M2 offers the ideal blend of aggressiveness for track use and the refinement expected in daily driving, making it a versatile solution. By utilizing the factory exhaust valve in conjunction with Dinan's muffler design, the system achieves a dual nature—aggressive and sporty during hard acceleration and subdued for city driving. This adaptability makes it highly sought after for drivers who need both performance and comfort.
Constructed from 100% 304 stainless steel and designed to precise specifications, this system ensures a perfect fit using the factory hangers and mounting points. It’s dyno-tuned for optimal exhaust flow and reduced backpressure, resulting in a deeper, more aggressive sound without the drone inside the cabin. The computer-controlled valve keeps the sound civilized during low-speed driving and opens fully during high-load conditions, effectively turning the exhaust into a straight-pipe system for maximum power and sound.
Dinan's quad black ceramic tips, laser-engraved with the Dinan logo, complete the system, providing both visual appeal and a high-performance look.
Key Features:
-
Power Gains: Maximum increase of +6 HP and +5 lb-ft of torque
-
Sound Profile: Sportier, more aggressive tone under acceleration
-
Quad Tips: 3.5" laser-engraved black ceramic exhaust tips with Dinan logo
-
Exhaust Valve Control: Computer-controlled valve limits noise at low speeds and opens fully under high load for free-flow exhaust
-
Straight-Through Design: When the valve is open, the exhaust flows straight through 3.25" tubing for maximum performance
-
Material: 100% 304 stainless steel construction for durability and corrosion resistance
-
Fitment: Uses the factory brackets and hangers for easy, OEM-like installation
