Center Resonator Delete/X-Pipe Kit - G80 M3, G82/G83 M4
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 G8X M3/M4 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 OEM valved muffler operation for factory 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
Installation:
Installation is as easy as cutting your factory exhaust, raising the new center resonator delete into position, and clamping. Click HERE for Installation Instructions. Product Development:
Our Resonator Delete/X-Pipe was designed, engineered, tested, and quality inspected by our Research and Development team at Turner. 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.
