Turner Z3M Performance Axle-Back Exhaust

Unleash your Z3M’s full potential with the Turner Performance Axle-Back Exhaust. Forget the heavy, restrictive factory exhaust — this system not only drops a significant 42 pounds but also provides a clean, aggressive tone that announces your arrival on the road or track.

Why Choose the Turner Z3M Exhaust?

While the E36 and E46 M3 models often steal the spotlight in the BMW performance scene, the Z3M, with its coveted S52 or S54 engine, offers an exceptional blend of power and handling. The Turner Axle-Back Exhaust embraces and enhances the Z3M’s capabilities, refining its sound, power, and aesthetic appeal for true enthusiasts.

With a straight-through muffler design, this exhaust optimizes exhaust flow, boosting throttle response, torque, and horsepower. Lightweight and meticulously engineered, it’s crafted to bolt right onto the factory mid-pipes for easy installation. Precision-designed for flawless fitment, it retains the OEM exhaust angle for a clean, OEM+ look.

Pro Tip: When swapping out your exhaust, check if your gaskets and mounts need refreshing for a completely seamless install.

Upgrade your Z3M’s shifting with Turner’s Dual Shear Selector Rod (DSSR). The DSSR provides a more solid connection, minimizing deflection and delivering a direct, precise shift feel. This meticulously crafted rod uses dual shear points to secure both ends of the shifter, translating every gear change into a crisp, controlled action — especially effective when paired with Turner’s poly rear shifter bushings.

Why Upgrade to the DSSR?

Imagine shifting with a single arm; you have control, but it’s limited. The DSSR uses both contact points, like gripping handlebars with both hands, offering a balanced and powerful connection. With its solid construction and minimized play, this DSSR keeps you firmly connected to your transmission for a completely immersive shifting experience.

DSSR Key Benefits:

Enhanced Shift Feel: Dual shear design for stability, minimizing unwanted movement. Perfect Fit: Precision-machined pins ensure seamless installation. High-Quality Materials: Constructed from 303 stainless steel for durability and corrosion resistance. Consistent Alignment: Maintains factory shifter length and angle for optimal ergonomics.

Tired of dealing with excess shifter slop and a mushy shifter? The Turner Shifter Rebuild & Upgrade Kits will restore your shifter's crisp feel and eliminate excessive movement that develops over time with wear. Included in this kit are all the common wear components and upgraded bushings that will give you a tighter shifting feel than traditional rubber bushings and will resist wear significantly longer.

This kit is perfect to restore your driving pleasure and will be the last shifter rebuild you will ever need!
