BMW G8X M2/M3/M4 (S58) CenCal Titanium Valved Catback Exhaust

Built for the S58 platform, our Valved Titanium Catback Exhaust delivers what factory exhaust systems can't: real weight savings, true sound control, and exhaust flow that matches the potential of your motor. Every system is hand-built from Grade 5 titanium and made to order right here in California.

Grade 5 Titanium Construction

Grade 5 titanium is the same alloy used in aerospace and motorsport applications. It's stronger than stainless steel at nearly half the weight, and it won't corrode or discolor over time. The result is a catback that sheds serious weight off the rear of the car while handling sustained heat and abuse better than any stainless system on the market.

Valved Sound Control

Go from quiet cruising to full-open aggression with the push of a button. The integrated valve system lets you control your exhaust note on demand, whether you're keeping it civil in the neighborhood or letting the S58 scream on the open road. Every system comes with the valve controller and all necessary hardware for a complete plug-and-play installation.

Optimized Exhaust Flow

This isn't just a louder exhaust. The entire system is designed to reduce backpressure and improve flow from the downpipes back. Better flow means sharper throttle response, faster turbo spool, and measurable gains in horsepower and torque. Pairs with stock, catted, or catless downpipes.

Precision Fit & Finish

Each catback is engineered for direct bolt-on fitment with OEM mounting points. A built-in flex section simplifies installation and absorbs drivetrain movement. Every weld is inspected, every joint is leak-tested, and each system is finished with a laser-etched CenCal logo.

Tip & Mid-Pipe Options

Multiple exhaust tip styles and mid-pipe configurations are available to dial in the exact look and tone you want. Whether you're going for understated or aggressive, there's a setup that fits your build.
