      Description

      Performance Exhaust System. The Flowmaster Dual Exhaust Kit, 2-1/2, Flowmaster True enhances your vehicle’s sound and performance with a balanced, deep exhaust tone. Designed for enthusiasts seeking improved throttle response, power gains, and a notable aggressive to moderate sound, it is engineered specifically for crossmember-back applications.

      Construction and Appearance. This exhaust system uses 16-gauge aluminized steel tubing that is mandrel bent for optimal flow and durability. The tubing features an aluminized finish to resist corrosion, paired with polished 304 stainless steel angled exhaust tips for a refined, high-quality appearance.

      Installation. Installation is straightforward with included hangers, U-bolt clamps, and hardware, requiring no drilling for a secure fit. Designed to replace crossmember-back exhaust sections, it offers a direct bolt-on solution that maintains factory emission compliance.

      Warranty. This exhaust system is backed by a 3-year limited warranty ensuring quality and durability.

      Application. Fits Chevrolet Camaro and Pontiac Firebird V8 engines from 1970 through 1974, specifically designed for crossmember-back installation without compatibility for other vehicle configurations or model years.
