Description

The Stone Exhaust Y352/Y283 catalytic downpipe is engineered to enhance the performance of Volvo V60/S60 T5/T6 2.0T vehicles, specifically those with the Y352 or Y283 chassis and a 2.0T engine (engine code B4204T9). This downpipe incorporates Stone Exhaust's patented 'eddy catalytic technology,' which uses an arc-packaging method to create a vortex effect during exhaust gas expulsion. This process purifies emissions, similar to a 400-cell catalytic converter in lower RPMs, while also generating significant torque. As RPMs increase, the vortex effect allows the catalytic converter to function like a 100-cell unit, resulting in a performance boost. Constructed from SUS304 premium grade stainless steel, this downpipe is built for longevity and resistance to corrosion. It features advanced welding techniques, including dual cross-welding at the turbo flange for increased durability under extreme temperatures (800℃ to 1100℃) and direct spot welding for enhanced product strength and precision. The O2 sensor technology design ensures real-time data performance, eliminating delayed power delivery. Stone Exhaust utilizes 3D scanning and computer simulation during R&D to achieve optimal pipe diameter, route, and bending angles, ensuring a 100% OEM fitment without requiring vehicle modification. This downpipe is compatible with the following Volvo models: Y352 V60 T5 (2014+) Y283 V60 T6 (2014+) Y283 S60 T6 (2016+) It comes with a 2-year warranty.
