Eddy catalyst
Meet the latest technology that adheres to the world's increasingly stringent environmental regulations at the same time enhances performance to another level.
In comparison to commercially available linear frustum, the "arc fluid eddy catalyst technology" adopts an arc-packaging method.
The turbine emissions process produces a vortex effect which purifies the exhaust gases while maintaining an equal amount of back pressure.
When compared to a variety of horsepower tests and straight downpipes, our patented arc fluid eddy catalyst technology can effectively increase horsepower and torque.

The Special Precious Metal and Packaging Technology from Stone Exhaust
For the environmental problem caused by the new generation of the turbo engine, especially on the rare metal content, Stone Exhaust has conducted a complete analysis and allocation.
In addition to containing a higher percentage of precious metal content in each section, while coping with bigger discharge pressure, the section will not fall off within the pipe despite longtime thermal expansion and contraction, thanks to our excellent packaging technology; this product manages to excel in environmental protection, performance, and durability.
