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.

This Supersprint center section replaces the stock facatory catalytic converter and includes a tuned center resonator. This Supersprint resonator was designed to replace the stock center section on Euro non-cat 1987 E30 M3s. This is a direct replacement for the stock cat and perfect if your cat is no longer needed or has failed. And with a free-flow design you can expect a 5-7hp gain over the stock cat section.
Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Unlock the full potential of your G87 M2’s exhaust with the Eisenmann G87 M2 Center Pipe Set, designed to significantly enhance both sound and performance. While the S58 engine already offers a sound improvement over the S55, the stock center pipes remain a limiting factor. The OEM setup includes secondary catalytic converters and dual resonators, adding unnecessary weight and dampening the exhaust note. Eisenmann’s resonated center pipes, weighing 10 lbs less than the factory version, provide a noticeable upgrade in both weight reduction and exhaust tone.
These center pipes are engineered to integrate perfectly with the Eisenmann Performance Rear Exhaust but can also be installed with the factory rear section, offering flexibility in setup. Available in both resonated and non-resonated configurations, the system converts the European-style slip-on design to the fully bolt-on system preferred by U.S. enthusiasts, ensuring easy installation and a secure fit.
For those who want to keep the stock rear muffler, the non-resonated option features an integrated x-pipe, replacing the bulky resonators. This configuration optimizes exhaust flow, delivering a more aggressive sound while shedding weight. It’s a cost-effective upgrade that enhances performance without requiring a full exhaust system replacement.
Optional Black Series Finish: For added performance and protection, the Black Series Ceramic Coating offers a high-temperature ceramic coating, improving heat dissipation and providing superior corrosion resistance, ensuring long-lasting durability and style.
