Grand Rock - 1994-2002 Peterbilt 379 Retro Fit Duplex Stack Exhaust Kit

The Grand Rock – 1994–2002 Peterbilt 379 Retro Fit Duplex Stack Exhaust Kit is a complete aftermarket exhaust solution engineered to enhance the performance and appearance of older Peterbilt 379 trucks. Designed specifically for 1994–2002 models, this retrofit kit replaces worn, single-stack, or OEM exhaust systems with a robust duplex configuration. The polished chrome stacks not only give your truck a striking, customized appearance but also deliver long-lasting resistance to corrosion, rust, and the harsh conditions encountered on the road. Whether restoring a classic rig or giving your truck a visual and functional upgrade, this kit offers both reliability and style.

Built with durability and ease of installation in mind, the kit includes all of the essential components needed for a complete exhaust conversion. With picket-style 90° elbows and 52" spool pipes, the system promotes efficient exhaust flow and balanced performance from both sides of the engine. Also included are lower cab brackets, stack mount brackets, and protective grommets to ensure secure mounting and minimize vibration. Pre-formed WFC-5Ss clamps are supplied as well, providing superior strength and a leak-resistant connection. Ideal for professional installers, fleet maintenance, or experienced DIY truck owners, this retrofit kit delivers dependable functionality and a bold look.
