Description
High-Performance Dual Exhaust. This crossmember-back true dual exhaust system is engineered to enhance power and sound for high-horsepower, large cubic inch V8 engines. Featuring mandrel-bent 3-inch aluminized steel tubing and an integrated H-pipe crossover, it delivers maximum power gain and a deep, aggressive exhaust tone while improving exhaust flow and engine efficiency for a commanding presence.
Construction and Appearance. Made of durable aluminized steel, the system includes large cased Super 40 Series chambered mufflers finished with black high-temperature paint, providing both a sleek look and long-lasting durability. The tubing is mandrel bent to ensure smooth flow and precise fitment, and the mufflers are designed for enhanced performance and sound control.
Installation. Installation requires moderate mechanical skill and uses the included mounting brackets, hangers, clamps, and hardware. It is a bolt-on installation from the crossmember back and does not require modifications to factory manifolds. Header reducers or downpipes for factory manifolds are not included.
Warranty. This exhaust system is backed by a 3-year limited warranty against defects in materials and workmanship.
Application. Fits 1967-1969 Pontiac Firebird V8 Models.
