Larini Catalyst Components

Larini 'Sports' Catalysts

For certain vehicles we produce high performance, Stainless Steel, Larini ‘Sport’ Cats.

Larini 200-cell sports cats replace the original catalytic converters, and clean emissions while permitting a significant power increase - without any technical or legal issues. The original lambda/heat probes connections ar 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-4/5 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 construction and a ‘Mirror Polished’ effect 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.

Larini 'Race' Pipes

The maximum. Larini ‘Race’ Pipes are high temperature resistant, hollow pipes, which replace the original bulky catalytic converters. The original lambda/heat probe connections are retained.

Exhaust flow is completely unobstructed through these 'pipe only' components and as result there is an extremely noticeable power gain. Temperatures are reduced too, as accelerated gas-flow minimizes engine-bay temperatures by dissipating heat more effectively. This is particularly important for improved performance, as cooler temperatures boost engine efficiency.

Furthermore, the muffling effect provided by the bulky stock cats is eliminated, subtly enhancing volume levels. 

Every Larini ‘De-Cat’ Pipe is supported by the LariniSystems Lifetime Warranty.

For off-road use only.

Larini 'Silenced' Race Pipes

Larini ‘Silenced’ Race Pipes are high temperature resistant, muffled pipes, which replace the original catalytic converters. The original lambda / heat probe connections are retained.

These innovative products deliver similar power increase as the ‘Race’ Pipes but are 'silenced' using mini-resonators to reduce volume for those who want more power, with only a slight increase in volume. Nevertheless, the ‘note’ and ‘tone’ of the engine are significantly improved. Just the perfect compromise.

Furthermore, torque increase is typically higher than that of a ‘Race’ Pipe as back pressure levels are modulated optimally.
