Turner Performance Exhaust Systems for Your G87 M2

Among the many reasons enthusiasts flock to the S58 is its unmistakable exhaust character. BMW’s twin-turbocharged inline-six delivers a fierce, motorsport-inspired snarl at wide-open throttle—yet the factory mid-section muffles much of that personality. The stock resonator and restrictive flow path tame the soundtrack, muting the aggressive tone your G87 M2 is capable of producing.

Turner Motorsport set out to change that. Their Resonator Delete transforms the factory system with a direct bolt-on mid-section engineered to free both sound and performance. By removing the bulky OEM resonator, integrating a true x-pipe, and shedding roughly 5 lbs of unnecessary weight, this upgrade enhances exhaust scavenging, sharpens throttle response, and unleashes a deeper, more engaging tone. Best of all, it retains full compatibility with the OEM downpipes and valved rear muffler—delivering a noticeable sound improvement while preserving factory functionality and easy reversibility.

Features:

Deeper, more aggressive exhaust note with added character and minimal drone

X-pipe design promotes efficient exhaust scavenging for improved flow

Maintains factory valved muffler operation and OEM-plus refinement

Approximately 5 lb weight reduction vs. the stock center resonator

Brushed 304 stainless steel construction with clean TIG-welded seams

Design:

1.25 mm-wall brushed 304 stainless steel tubing

76.2 mm (3") diameter

304SS sleeve-style and Accuseal clamps with slip-joint adjustability

Nothing but the highest level of precision and quality through leading-edge product development technology including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

Performance Cat-Back Exhaust for pure unrestricted power and sound. This exhaust takes out all of the stop gates and pairs with the S58 for an iconic driving experience.

The G87 is no stranger to performance. Right out of the box the new M2 features rocket-like acceleration, and great handling and is even offered with a manual gearbox. With our Turner Performance exhaust you get a more engaged feeling improving the driving experience. Increased sound you can both hear and feel offers a direct line of feedback between you and the car. The added volume allows you to feel where you are in the power band without looking at your rpm gauge allowing you to feather the exhaust around turns and when shifting in your manual transmission. Along with the increased volume and feeling our exhaust features smooth transitions and improved flow for improved throttle response and sound on deceleration.

Our mission was to amplify the G87 with a proper Cat-Back exhaust system. To accomplish this goal, our engineers increased flow, reduced weight by 27 lbs, and delivered an exhaust system that captures the full unrestricted sound of the twin-turbo inline-6 S58 engine. The increase in flow was gained from dual 3.0" 304 stainless steel exhaust pipes that feed into a free-flowing rear section. We specifically designed this catback with flow in mind to ensure the exhaust would never be a restriction. Weight reduction is achieved by replacing the factory piping with lightweight 304ss for a more-than-modest weight advantage free from the added weight of the bulky factory muffler. The best part of the Race-Inspired Cat-Back is the capability to perform far beyond the point that the factory exhaust. All of this plus the direct fitment and straightforward installation leads to our Turner Race Inspired Catback exhaust being the clear answer in your mission to find the best exhaust for your S58-powered M2.
