Exceeding 24 years in the exhaust industry, no doubt, Stone Exhaust has cumulated elusive insider knowledge and craft techniques in the forging of the market’s finest exhaust systems ever created.

Stone’s remote-controlled valvetronic exhaust system

Stone Exhaust USA’s cognizance in constructing top-performance exhaust systems has led them to acquiring five of their own in-house developed patents. Their transmission components are designed through the CNC Process which ensures systemic soundness throughout the exhaust system.

Furthermore, Stone Exhaust’s valvetronic systems are optimized for heightened horsepower and torque, which produces a signature sound that feels more like eargasm than actual noise. These exhausts override traditional construction of wiring and rubber inside the valve to extend the exhaust life and curtail corrosion.

At the SEMA Show Las Vegas 2019, Stone unveiled its M3 and M4 valvetronic systems and provided interested parties at the premier automotive show a real-time experience of Stone’s signature sound.

Indeed, Stone Exhaust USA stands by innovation, the catalyst to their lifelong quest to deliver superior quality exhausts.

Apart from that, Stone Exhaust’s valvetronic remote control allows customers the ease of switching modes from ON to OFF to AUTO, which comes with a predefined RPM based on on-road tests.

This flexibility owes to one of the pinnacles of Stone’s foundation- to investigate, innovate, and respond to customers’ needs. All are done with one goal in mind: to offer only the best products to valvetronic exhaust shoppers in the USA and beyond.
