The purpose of the Mini Cooper Exhaust System is to dispose of waste gases from the cylinders. Today's high-tech exhaust system has many different components which actually work in concert with the fuel system in order to maximize fuel efficiency while minimizing harmful emissions. If any part of your Mini Cooper Exhaust System is damaged or faulty, your vehicle's engine performance can suffer, and it may put out more in the way of polluting exhaust.

The modern exhaust system begins with the header, or "exhaust manifold," which collects exhaust gas from the cylinders. The exhaust gas is then processed through the catalytic converter.

This removes carbon monoxide, hydrocarbons and nitrous oxides through use of a platinum "catalyst" that breaks molecular bonds and recombines them into relatively harmless compounds. When this is defective, foul smelling exhaust will result, and your vehicle may not meet emissions standards of many states and local municipalities. On its way to the muffler, the exhaust is analyzed by the oxygen sensor. This device sends electronic signals to the fuel injectors, which adjust the fuel mixture for varying driving conditions. The next part of the Mini Cooper Exhaust System is the muffler. This reduces the noise of the cylinder explosions. A defective or damaged muffler will cause your car to sound like a giant lawn mower, and may put it in violation of local noise ordinances. The exhaust finally exits through the tip, or tailpipe. Since they're located underneath the car, your exhaust system components are subject very harsh conditions that make them subject to damage and wear.Browse our catalog for the lowest prices on Mini Cooper exhaust manifolds, catalytic converters, mufflers or exhaust pipes.
