Exhaust system mounted without applying thermoset pastes and new mounting parts may cause a leak. Moreover, exhaust fumes may get inside the car causing discomfort when driving (headaches), faster fatigue of the driver or even loss of consciousness which can lead to an accident.
GD 12 company recommends elements built of materials that meet all the EU standards.
Wrong choice of the silencer or any other element of exhaust system (that is not recommended by the manufacturer for a given car) may cause negative effects of using it, like for example decreased combustion efficiency, decreased engine power or even engine seizing.
FERROZ exhaust systems meet all recommendations and specifications of car manufacturers.
When mounting rear silencer it is recommended to check if the middle silencer is not damaged, too. Corroded elements may blow out of it, damaging the new rear silencer.
Practical tips cencerning exhaust system mounting:
-the mounted exhaust system should not be stretched or tightened
-a special aerosol that is resistant to high temperature should be applied on the screws
-high-quality gaskets should be placed on every join
-rubber hangers should be replaced when mounting new silencer (even if they seem to be not damaged yet)
-every hook should be additionally protected by a cotter, so that the hanger couldn’t fall down
-clamp should be mounted to the chassis at first, after that, silencer
-when linking two pipes together thermoset paste should be applied on the outer side of the smaller pipe, so that it is pushed outside the silencer, not inside
-schackles should be mounted in the middle of the join of two pipes. They should never be the lowest parts of the whole exhaust system.
Exhaust system should be dismantled starting from the rear side of the car.
Every time while dismantling, it should be checked if the hooks or catches are intact.
It often happens that some elements ,that were chosen incorrectly, are mounted by force which causes the damage of the hooks or catches.
If such a problem occurs the owner of the car should be informed about that immediately.
In such a situation, there may be a need to bend the hooks or other parts again, so that the new exhaust system (which is chosen correctly) can be mounted without any problems.
It is not recommended to interfere in the elements of the suspension, therefore new silencers should be chosen correctly and be suitable for a particular type of the car.
