Can the TT system be supplied with catalysts?

0

We are investigating the possibility of adding low loss catalysts in the position normally occupied by the first silencer boxes to satisfy the requirements of some markets where a visual catalyst check is mandatory. It is not practical to incorporate catalysts further forward in a twin pipe system but a lambda feedback sensor (heated type) can still be used which means most cars will still pass a yearly or biennial emission test without the catalyst being present.. Contrary to some beliefs UK cars do not have to have a catalyst to pass an MOT test.
