Detailed Product Description

The Dynomax Ultra Flo Welded Single System exhaust kit (39495) is a cat back system designed to replace the exhaust components from the catalytic converter back. Featuring a 3-inch pipe diameter made from stainless steel, this system ensures durability and resistance to corrosion. The mandrel-bent pipes maintain consistent diameter through bends, promoting smooth exhaust flow and reducing backpressure. The system includes a single muffler with a natural body finish and a polished round tip that exits at an angle with a straight style, providing a clean and functional look.

This exhaust system kit comes complete with all necessary components: intermediate pipe, muffler, tail pipe, tip, and two band clamps for secure mounting. The aluminized finish on the body enhances corrosion resistance while maintaining a natural appearance. The kit is engineered for performance applications, making it suitable for drivers looking to maintain or improve exhaust efficiency on their Chevrolet Silverado 1500 or GMC Sierra 1500.
