G87 M2 Performance Valved Cat-Back Exhaust & Carbon Cold Air Intake System
Maximize your M2’s performance and sound without breaking the bank! This Doorbuster pairs our valved cat-back exhaust with a carbon fiber cold air intake for a complete upgrade, delivering 7 WHP and 9 ft-lbs of torque in the mid-range.
PERFORMANCE VALVED CAT-BACK EXHAUST - G87 M2
The all-new M2 already impresses, but we take it further. Our valved cat-back exhaust system unlocks the full character of the S58 twin-turbo inline-six—offering a deeper tone, quicker response, and a more visceral connection to the car. Designed and engineered in-house, the Turner exhaust provides a 27 lb weight reduction, increased flow, and a dynamic sound profile that transitions seamlessly between mild and wild via factory valve control.
Constructed from 3.0” mandrel-bent T304 stainless steel, this system is TIG-welded, back-purged, and built to endure. An integrated X-pipe enhances scavenging and balance, while strategically placed slip joints ensure perfect fitment. Whether you’re carving corners or cruising the highway, the Turner system delivers the soundtrack your M2 deserves.
Key Features:
Dual 3.0” T304 stainless steel mandrel-bent piping
27 lb weight savings over OEM system
Valved muffler for switchable tone and sound control
Precision laser-scanned and CAD-engineered fitment
TIG-welded construction with 12mm barbed hangers in OE locations

CARBON FIBER COLD AIR INTAKE SYSTEM - G87 M2
At Turner, all our Carbon Fiber Intake Systems are top-of-the-line custom-engineered products that we develop in house. Our G8x Intake is no exception. Turner Carbon Fiber Intakes start with a 3D scan of the factory intake and engine bay. Our engineers use these 3D images of the chassis to design the intake in SolidWorks modeling software. Using a Flow Bench, our Intake is then airflow tested against the factory intake, to ensure optimal airflow improvement against stock. The final product is a beautiful and functional Carbon Fiber Intake, CAD designed for perfect integration with the OEM inlet ducting and stock mounting locations and proven to flow better than factory.
Our G8x carbon fiber airbox sport entirely carbon fiber construction, with a removable carbon fiber lid for easy air filter access. Our enclosed carbon fiber intake systems are also proven to lower intake temps vs. open filter intakes. Plus, they further enhance the appearance of the engine bay, by adding more beautiful carbon fiber. The carbon airbox and lid is manufactured using 2X2 twill weave carbon fiber and protected with a gloss finish clear coat for UV resistance. The Best part? The airbox mount in the stock location with all supplied hardware included.
The oval intake tube design matches the OE look, allowing the intake to be used with the factory structural brackets that the intake goes through. However, the cross-sectional area of the Turner Carbon Fiber intake tube is greater than the stock intake tube, with a smooth interior for even better flow. The carbon intake tube is manufactured using 2X2 twill weave carbon fiber, and the intake tube is protected by a gloss finish clear coat for UV protection.
With the oval design of the intake tube, the custom air filter had to be designed for this intake system. The air filter is specially designed to seal against the carbon fiber airbox, eliminating any opening for hot air to enter the airbox! We created a conical hi-flow reusable air filter; featuring 8 ply oiled cotton gauze construction to maximize filtration efficiency. This filter features a Bellmouth (velocity stack) filter flange inlet to reduce turbulence in order to maximize flow.
Overall, the less restrictive intake design allows for more flow to the engine. The Drivers side Stock intake flows 336.2 CFM @ -15 inH20. The Drivers side Turner intake flows 374.3 CFM @ -15 inH20. This is about a 12% increase over stock The Passenger side stock intake flows 274.2 CFM @ -15 inH20.The Passenger side Turner intake flows 296.3 CFM @ -15 inH20. This is about an 8% increase over stock. Flows over 10% more air than factory intake system!
