The factory catalyst section incorporates a large divider internally running down the center of its pipework. This is to regulate excessive back pressure levels for the restrictive OE exhaust. This arrangement saps power.

The Larini Silenced De-Cat Pipe replaces the massively restrictive factory catalytic converter, with 'straight-through' pipework, wrapped in a mini resonator. This product delivers similar power increases as the de-cat pipe, but is 'silenced' using a mini-resonator to reduce volume for those who want more power, with only a slight increase in volume levels.

Vastly freer flowing in comparison to the standard catalytic converter.
Direct bolt-on replacement for the OE catalyst.
Pipework and bosses are fully 'Satina' Polished and 'Lime Chalk' waxed.
Mandrel bent pipe work allows a constant internal diameter, maintaining a smooth, constant gas flow.
Constructed using aircraft grade T.316 Austenitic Stainless Steel.
100% TIG welding construction.
Correctly positioned, heat-distortion resistant, CNC-machined stainless steel Lambda bosses and heat probe connections.
Precision engineered for accurate fit.
Requires no special procedures to fit.
The original heat shielding is retained.
