We offer Stainless Steel ceramic coated Sport catalyst replacement sections.

These section uses a lighter 200 cpsi core which improves flow for the exiting exhaust gases which in turn improves engine performance.

Sound is also improved offering a crisper pitch throughout the rev range which is relative to throttle position.


Our Polar White Coating offers temperature reductions of over 110 degrees C at the manifold, resulting in a reduction of over 27.5 degrees C in under bonnet temperature and power increases of up to 5.5%. The coating originally developed for the defence and Nuclear industries offers proven performance gains and isextremely durable and stone chip resistant.

Now used extensively in top level Motor Sport our Ceramic Coat option offers greater performance / reduced surface and ambient temperatures / highly effective corrosion barrier and a tough hard wearing shell coating whilst adding a truly unique look and finish to your system.
