Cat® Mufflers reduce the amount of noise emitted by the exhaust of an internal combustion engine. Every time your exhaust valve opens, a large burst of burnt gases used during your engine's combustion is released into the exhaust system. This release of gases creates very powerful sound waves. Cat® Parts are manufactured to precise specifications and are built for durability, reliability, productivity, and less environmental impact.Applications:Consult your owner's manual or contact your local Cat Dealer for more information.
