We can also provide standard pattern stainless systems for most applications on request.

Exhaust Emissions. Contrary to widespread belief the UK MOT does not require a catalyst to be present, only that the car does not exceed the maximum gaseous emission levels specified for its year, which most cars will easily achieve without need of a catalyst. As an example the purpose of the Lambda feedback system of any modern catalyst car is to control the fueling so that the %age of CO in the exhaust before the catalyst is never more than about 0.1%. If it rises above this level the presence of a catalyst will reduce it but it is actually a symptom of a fault that is likely to eventually destroy the catalyst. As the UK pass level is either 0.2% or 0.3%, depending on the circumstances, the absence of the catalyst will not prevent a healthy car from satisfying the test. Much the same applies in other parts of the World including the USA although if a check includes a mandatory visual catalyst inspection then clearly the situation is slightly different.

Tail Pipe Trims. For many people the tail pipes are an important part of any exhaust system simply because everything else is out of sight and they alone provide a visual impression to the outside world.

Our complete systems include polished tailpipes that we feel compliment the rest of the product but this can be very much a matter of personal opinion. Some people don't want tail pipes that look overtly different, some prefer them to be different but subtle, others may want them to be outrageous.

We therefore offer a number of alternatives in terms of style and size for many of our systems. Options include round, oval or square; rolled in, rolled out, or sawn, all at various angles; various sizes from reserved to absurd; and finally single or dual outlet. The photograph shows some examples. Pricing may vary depending on the choice.

Lambda fitting bosses and Lambda sensor extension wires are included where necessary. Fueling (ECU program) modifications are also included where necessary. A fitting kit of clamps, sealing olives, etc. is included with major systems but not normally with Silencer Substitute Pipes and Mini Silencers.

The following pages list the various applications. Prices can be found under the respective model headings in our main price list. If in any doubt about your particular car please phone and we will help to verify the exact requirement with respect to model, year, and market specification.
