Do You Know About The Parts Of An Exhaust?

Exhaust Manifold/Header

This is the first point of contact for the exhaust gases after they exit the cylinder head. It’s also a commonly upgraded item where heavy cast manifolds are swapped out for tubular headers. 

The idea behind upgrading to an exhaust header typically comes down to increasing the exhaust piping diameter as well as increasing exhaust scavenging by aligning the exhaust pulses in a favorable fashion. If you are looking for the best exhaust system then it would be highly recommended to use empire exhaust systems for your vehicle.

Catalytic converter

This is the device that allows you to still breathe the air while you’re visiting Los Angeles. It takes the incoming NOx, CO, and unburnt hydrocarbons from the exhaust and “converts” them into much less harmful N2, O2, CO2, and H2O.

Piping

It’s ideal not to have your exhaust gases pump directly underneath your car, filling your cabin with fumes. You’ll need some pipes to route the air elsewhere.

Resonator

Though it’s not a necessary portion of exhaust, it’s often included as it helps to eliminate noise. Resonators work by rejecting sound waves and canceling each other out, and they’re typically tuned for a specific frequency in which the engine noise is loud or undesirable.

Muffler

There are many types of mufflers, but the goal is pretty much the same: eliminate noise. One of the most common ways they work is by redirecting the airflow. Along the way, the exhaust passes through porous pipes which allow the exhaust gases to expand into sound deadening material, minimizing the noise that finally exits the tailpipe.
