The MagnaFlow Street Series Cat-Back Performance Exhaust System 16830 is designed to bring out the true personality of your 1975–1981 Pontiac Firebird equipped with 4.9L, 5.0L, 5.7L, or 6.6L engines. It delivers MagnaFlow’s signature deep, resonant exhaust tone combined with dyno-proven performance.
This exhaust system features 2.5-inch fast-flowing mandrel-bent main piping that passes through dual straight-through mufflers, finishing in a dual split rear exit with 2.25-inch polished clamp-on single-wall turndown cut-edge tips. The result is a classic sporty appearance paired with a refined yet powerful exhaust note.
Engineered to produce moderate exterior sound levels and mild interior sound levels, this system enhances driving enjoyment without sacrificing comfort. The Street Series tuning makes it ideal for both relaxed cruising and spirited driving.
Exhaust kit 16830 utilizes a cat-back configuration, replacing the factory exhaust system from near the catalytic converter back. Extensive 3D scanning during development ensures a precise direct-fit design for easy do-it-yourself installation. Manufactured using CNC precision robotic techniques and built from durable stainless steel, this system is backed by MagnaFlow’s 1-year limited finish warranty and limited lifetime construction warranty.
