EXHAUST PRODUCT MATERIALS

A number of different materials are found in exhaust systems. Often different options are available for use in a single application. Since materials vary in strength, corrosion resistance and price, a particular material may be preferred in certain applications. Some of the most common materials, their qualities and their typical uses are as follows.

Aluminized Mild Steel
Used in Mufflers and Exhaust Components offering good corrosion resistance.

Stainless Steel
Used in flexible tubing, mufflers, exhaust components and emissions products offering stronger and excellent corrosion resistance.

Chrome
Used in accessories to offer bright mirror finish.

Galvanised
Used in flexible tubing for low material cost and temp limits of 600º F 

Cold Rolled
Used in accessories with poor corrosion resistance and low cost.

PURPOSE OF AN EXHAUST SYSTEM

Exhaust system design specifications are typically defined by the OEs. They are looking for a solution that can redirect engine exhaust, reduce exhaust noise and most recently, reduce emissions (hydrocarbons, carbon monoxide, soluble organic fraction (SOF)). Diesel engines are a reliable and efficient power source for vehicle and equipment manufacturers. Governmental regulations across the globe are driving diesel engine users to consider buying new vehicles to meet the new emissions regulations.

MUFFLER DESIGN AND PERFORMANCE

Mac Industrial Exhaust Systems are designed and tested with specific focus on three performance variables: attenuation, backpressure and structural. Attenuation For exhaust systems: attenuation refers to the reduction in sound level measured between an engine without a muffler and the same engine with a muffler. This sound level is typically measured in a decibel scale (dBAs). Traditional mufflers use tubes, baffles, expansion chambers and insulation to help control noise.
