If you are thinking about enhancing your vehicle's exhaust system, you should consider choosing custom fabrication. In general, there are multiple advantages attached to installing a new high-performance exhaust system. This improvement will facilitate faster removal of exhaust gases, ensuring that he engine can draw in clean air faster. Consequently, the horsepower and the fuel economy of your vehicle will improve considerably due to better combustion of the fuel. In addition, a high-performance exhaust module will enhance aesthetics by improving the sound and general style of the vehicle. Here are the primary factors to consider during the custom fabrication of an exhaust system.

Exhaust System Type

There are different types of replacement exhaust products, and your choice will determine the level of enhancement and the cost of the fabrication project. Typically, the types of exhaust are classified according to the parts of the exhaust system which will be replaced. Header-back exhaust systems are designed and built to replace all the components from the header collector up to the tail pipe. This will allow you to enlarge the entire exhaust system, so the addition will enhance fuel economy, power and sound. Unfortunately, the total cost is extremely high.

The cat-back system is less expensive and it replaces the components from the catalytic converter to the tail pipe. The effect on fuel economy and performance is only moderate, but the improvement with regard to style and acoustics is significant. The axle-back exhaust is the least expensive because it only replaces the components from the rear axle to the tail pipe. This is not the best option for performance; the effects on fuel economy and the horsepower are minimal.

Structural Material

When fabricating a custom exhaust system, you must choose the right material for your project. In general, all the materials used for this type of material are based on steel. Mild steel products are the least expensive because the material is inexpensive to purchase. Moreover, the low carbon content means that the metal is relatively easy to form and fabricate. Unfortunately, mild steel is prone to rust and general degradation. For longevity and enhanced performance, you should choose stainless steel. It is durable and resistant to rust.

Exhaust Configuration

You can choose single or dual exhaust configurations for your vehicle, depending on your preference. The single design has one exhaust tip which exits from the muffler while the dual alternative has two exhaust tips. The former is lighter and less expensive. However, many people like the dual option due to the enhanced appearance.
