Stone Exhaust Eddy Catalytic Downpipe (Non-OPF) – B48

Product Details

Since 1998, STONE Exhaust Systems has been driven to developing and refining the most advanced exhaust system technology that provides a boost in performance while still retaining reliable durability. Throughout the years, this has led STONE to developing technology such as their “eddy-flow” catalytic downpipes which are molded based of 3D printed OE downpipes to ensure a direct fitment without requirements of any additional modifications.

STONE Exhaust’s Eddy Catalytic Downpipe utilizes their patented “eddy catalytic technology” which adopts an arc-packaging method. With its unique internal design, the downpipe 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, STONE’s eddy catalytic technology can effectively increase horsepower and torque.

Features:

• Patented O2 sensor technology design provides real-time data performance by accurately sensing every rotating displacement. No more delayed or error code problem.
• Special 3D design able to achieve a perfectly matching model with the original pipe. The same installation applies, no need to modify.
• SUS304 Stainless steel.
• Dual Cross-Welding Technology providing substantial increase durability.
