Detailed Product Description

The Dynomax Ultra Flo Welded Single System exhaust kit is engineered to replace the factory exhaust on Jeep Grand Cherokee models from 2002 through 2004. This cat-back system features mandrel-bent steel pipes that maintain consistent diameter through bends, improving exhaust flow and reducing restrictions.
