The 111R 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 De-Cat Pipe is a high temperature resistant, hollow pipe, which replaces the highly restrictive OE catalytic converter. Exhaust flow is completely unobstructed through this 'straight-through' component 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 cat is eliminated, subtly enhancing 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.
- Supported by the Larini Systems Lifetime Warranty.
- 5 lbs lighter than stock cat pipe (weighs only 5lbs!)
