This Supersprint downpipe is designed to be a plug and play upgrade. It replaces the stock components without any modification. O2 sensor plugs and mounting brackets are in the same position as the OEM unit.

The catalytic converter is a 100 CPSI unit, with a metallic honeycomb and a high content of noble metals. The shape and volume have been decided for optimal efficiency, thus the generous size.

The high amount of noble metals avoid any irregularity in the pollutant emissions, any warning light (CEL), any problem during periodic tests or bad smell, like it happens with cheaper cats.

The flex joint is the best on the market for durability and to guarantee free movement to the engine.

This special part has the main role in the performance increase of the Supersprint exhaust system, and it's perfect to for an engine tuning program.

Threaded bung for oxygen sensor provided.
