BMW's original muffler hanger (part number 18201401797) works great at first but tends to fail over time, leading to sloppy exhaust movement and excessive noise. This failure is due to both heat and the heavy exhaust wearing down the hanger until it eventually tears, allowing the exhaust to shift around freely, banging off of nearby components. In order to address this common problem, Powerflex developed their own polyurethane rear muffler hanger that features a heavy-duty, yet lightweight, machined aluminum bracket. Polyurethane is significantly more resistant to the effects of heat and weight over time compared to rubber, meaning you can expect this exhaust hanger to last many times longer than your stock BMW hanger.

Why own the only V8-powered M3 if you can’t actually hear it? BMW's E9X M3 features a hefty rear muffler assembly that silences the S65's distinctive soundtrack. While full cat-back systems can require a serious financial commitment, our new Muffler Delete Kit offers an affordable, no-compromise solution that brings your M3 to life!

This system transforms the character of your S65 by replacing the restrictive factory mufflers with a free-flowing, TIG-welded stainless steel assembly designed to amplify tone, shed weight, and preserve OEM fit and finish. Our design features dual 2.5" primary tubing that flows into adjustable 3" quad tips, creating a clean yet aggressive aesthetic. Up front, factory-style V-band flanges connect directly to the OEM midpipe—meaning no cutting of factory exhaust piping. At the rear, Accuseal slip-fit connections allow perfect tip alignment within the factory diffuser, ensuring a tailored, symmetrical look every time.

FEATURES

TIG-welded dual 2.5" primary tubing transitioning into adjustable 3" quad tips for a bold, refined appearance

OE-style V-band flanges for true factory-like integration—no cutting required

Accuseal slip-fit joints for full adjustability and precise tip placement

Utilizes factory hangers for a clean, bolt-on installation with zero drilling or modification

Our Rear Muffler Delete Kit is the result of advanced engineering, testing, and quality assurance by Turner’s Research & Development team. Every stage of development employs FARO laser scanning, SolidWorks 3D CAD modeling, and in-house rapid prototyping for precise fitment and design validation. Performance and durability are proven through Mustang AWD 500 SE dyno testing and Superflow SF-750 Flowbench analysis, ensuring each component meets Turner’s uncompromising standards for performance and quality.

Version 2 of the Valvetronic Designs E9X M3 Valved Exhaust System delivers significant upgrades in both reliability and sound refinement, making it the benchmark choice for the platform. We’ve returned to vacuum-actuated valves—proven to be more durable and consistent than electronic alternatives, and enhanced the exhaust tuning for a purer, more engaging driving experience. Constructed from premium brushed T304 stainless steel and fully mandrel-bent for maximum flow, this system offers the flexibility to cruise quietly with valves closed or unleash the raw S65 V8 soundtrack with valves open. For too long, premium valved systems have been out of reach for many enthusiasts, our mission has been to change that.
