PUK V8 Cat Pipes

• Deliver an extra 15-20 bhp (very conservatively spoken !!).
• Deliver an extra 23 lb-ft of torque.
• 200 cells per square inch for maximum flow with minimal backpressure.
• No adverse legal, environmental or technical implications
• Guarantee a more free-revving engine with improved throttle response
• Significant horsepower gains and increase in torque.
• Engineered for maximum flow efficiency, using complex internal Cat ‘cores’ (Metalith).
• Parabolic megaphone inlet cone design guarantees even flow distribution across the Metalith core - whilst minimizing packaging length.
• Reversion pulse outlet cone activates catalytic material for full length of the Metalith.
• Ultra durable T.316 Austenitic stainless steel heat casing protects components from heat distortion.
• Each 'individual' Cat is rated up to 300 bhp.
• Mandrel bent pipe work allows a constant internal diameter, maintaining a smooth, constant gas flow. 
• Vastly freer flowing in comparison to the standard ceramic cats.
• Pipework, bosses and Cats are fully 'Mirror Finish' Polished.
• 100% Tig welding construction.
• Correctly positioned, heat-distortion resistant, CNC-machined stainless steel Lambda bosses
• Precision engineered for accurate fit.

• The original lambda probes are retained in their correct positions for the proper operation of the OBD II (On Board Diagnostics II) system.

The stock V8 catalytic converters have 600 cells per square inch (cpsi). These original ceramic cats are VERY restrictive in their flow, only allowing an open area of approximately 55%. A PUK 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 virtual elimination of backpressure, allowing the engine to 'breathe' and perform better. Due to the removal of the 'sound - deadening' stock cats your Esprit will now sound as it should - phenomenal.

PUK Sports Cats clean the Esprit V8’s emissions while permitting a significant horsepower gain and a huge increase in torque. Unlike illegal De-cat/Test Pipes, there are no negative technical consequences associated with fitting these innovative products - the original lambda probes are retained in their correct positions for the proper operation of the OBD (On Board Diagnostics) system.

PUK Cats are Euro-3 emissions level rated - making it possible for vehicle tuners to obtain high power gains, whilst meeting government emission levels and staying road-legal with high reliability.

Pipework, bosses, Lambda probe connections and Cats are all ‘Mirror Finish’ polished. Our System fits perfectly to the manifolds and mounting points, requiring no special procedures or modifications.
