The GM exhaust system is one of the most frequently rejected parts of a vehicle. This is because most people tend to focus on body and engine improvement. However, what most people don't know is that the exhaust system performs a very important role. Vehicles create harmful gases during the combustion of fuel. The GM exhaust system carries harmful exhaust gases away from the passenger compartment and also converts most of the harmful gases into acceptable by-products. Moreover, it helps in reducing the sound made by the internal combustion engine, reduce the temperature of the exhaust and control the emissions that come out of the vehicle.
How does the GM exhaust system work? The begins with the exhaust manifold on the engine. Hot exhaust gases flow from the manifold through the front or header pipe into a catalytic converter. The converter changes unburned hydrocarbons (fuel) and carbon monoxide into water vapor and less harmful carbon dioxide. Inside the stainless steel case of the converter, there is a ceramic honeycomb coated with a thin layer of platinum. When the exhaust gases pass through the hot converter, they are changed. From the converter, the exhaust flows through another pipe to the muffler. On most cars, the exhaust now flows out the tail pipe, but on some models, the exhaust passes through a secondary muffler called a resonator. Finally, clamps and rubber mounts called hangers support the exhaust system under the vehicle.
Rocks, dirt, and mud affect the performance of the GM exhaust system. If there is less power, foul odors, or odd noises coming from the muffler, it might be time to replace the GM exhaust system.
The GM exhaust tip is one accessory that is designed to enhance a GM vehicle's appearance and to help in the exhausts systems performance. It adds a bit of style and uniqueness to the tail end of a car and it can also actually affect the volume of the exhaust tone. The larger the , the more volume that one will get from it.
GM exhaust tips are available in various types, styles, and sizes. They are either resonated or non-resonated. Non-resonated tips are just plain stainless steel tips. The resonated tips are lined with fiberglass to dampen the exhaust noise a little further. Sizes range from 2 inches to 5 inches wide. Styles to choose from include round, oval, square, slashed, etc. Exhaust tips can either be welded on, or if possible, clamped on.
