Tube Africa

The tube afrique indicates a metal end of Tuyau which replaces the catalytic Pot of a voiture.
It is also called Décatalyseur

This small tube has for only function the replacement of the catalytic pot, and does not treat in any way exhaust fumes: its function is to leave them the free field:)

For little which one finds an Africa tube with same dimensions that the catalyst, its installation will be summarized has 4 screwings/unscrewings of nuts and with 15 minutes.

The catalytic Pot, having for goal to reduce the pollution of producedes gas by the engine, is indeed subjected to two controversies:

  1. the Heavy metals which they contains pourraient to be detached and pollute the atmosphere 10 times néfastement than the cleansing effect. That arrives when the catalytic pot is subjected to many shock, when it is old, or when it is badly conçu.
  2. the gases of emission of the engine are slowed down by catalyst, generating a small lose speed (approximately a driving horse, and notorious losses of recovery)

Although the profit speed is often the principal motivation of the installation of an Africa tube (it is as less expensive as a catalyst in the event of replacement of this last…), le catalytic pot is obligatoire for the Voiture S circulating in many rich countries, it is in particular the case of France.
The installation of an Africa tube, pirate, is thus often illégale.

Mimétisme
This legal question pushes certain Africa tubes to adopt a perfect resemblance to new the pot catalytic.
