Fire means smoke and smoke or emissions are produced by the controlled explosions in the car’s engine. The exhaust system of a car is supposed to remove these emissions and clean them as much as possible before releasing them into the atmosphere. When the car’s exhaust system does not do this job then it has to be replaced.
Some of the components of the best 2009 wrx exhaust can be simply replaced with a wrench but others need welding equipment. Clamps can be used to cinch down joints between components. Working on the exhaust system requires getting it up on safety stands, blocking the wheels, and crawling .
Manifold Life of an Exhaust System
The exhaust system collects exhaust gasses as they leave the cylinders of the engine and then those gasses are piped to the catalytic converter through the exhaust pipe. Cars with all cylinders have one exhaust manifold. The exhaust system can become cracked or warped from excessive engine heat.
If the exhaust is escaping from places it didn’t before then the exhaust manifold may need to be replaced. Mostly the gasket seals between the manifold and the engine block have to be replaced when repairing an exhaust manifold.
