Smart Performance Exhausts
Your Smart Exhaust can be completely replaced or, depending upon condition we can replace any problem sections:
- Smart Manifold
- Smart Front Downpipe
- Smart Centre Section
- Smart Rear silencer box
Smart Silencer Or Back Box
Smart Silencer Or Back Box normally needs replacing first.
Fuel combustion in your Smart engine creates water vapour. As it passes along your Smart's cold exhaust pipes it condenses back into liquid water.
Sulphur and Nitrogen Oxide gases passing through you Smart's catalytic converter are absorbed by the water creating Acidic moisture that can attack the steel of your Smart exhaust.
Your Smart Silencer is the last part of the exhaust system to be heated and on short journeys may not heat up enough to eliminate the acidic condensation.
A problem with your Smart backbox will give a loud roaring noise as the silencer ceases to be effective.
If your Smart exhaust is rattling then a support bracket or rubber mount may have corroded or come loose. The rubber on your Smart exhaust hanger can become brittle and snap leaving your Smart exhaust system hanging loose.
Cracks in the exhaust pipes and failed gaskets, blockages all create unusual sounds so if you suspect that your exhaust is less than perfect it's best to have it checked.
