Larini 200-cell sports cats replace the original secondary catalytic converters, and clean emissions while permitting a significant power increase - without any technical or legal issues. The original lambda/heat probes connections are retained in their correct positions for the proper operation of the OBD (On Board Diagnostics) system.
Original vehicle manufacturer catalytic converters typically have 600 cells per square inch (cpsi). These original cats are restrictive in their flow, only allowing an open area of approximately 55%. A Larini ‘Sports’ Cat, alternatively, has only 200 cpsi, an open area of 90%, and offers near unopposed gas flow. The resulting increase in flow rates - with a modulation of backpressure, allowing the engine to 'breathe' and perform better.
Larini ‘Sports’ Cats are Euro-5+ emissions level rated - returning cleaner emission results than most standard catalysts, making it possible for vehicle tuners to obtain high power gains, whilst meeting government emission levels and staying road-legal with high reliability.
Lightweight, precise, construction ensures fit and finish are vastly superior to the bulky original items.
NB: Vehicles registered on or after 1st August 1992, are required to have a fully functioning catalyst fitted in order to comply with U.K. MOT test requirements. (Many other countries have similar requirements).
