Product Details

Magnaflow is well-known for creating exhaust systems that give vehicles a distinct, powerful sound and improved performance. This Street Series Cat-Back Performance Exhaust System is specifically made for your 1975-1981 Pontiac Firebird, designed to bring out the personality of its 4.9L, 5.0L, 5.7L, or 6.6L engine. It replaces your stock exhaust from near the catalytic converter back, giving you a noticeable upgrade in both sound and power.

This system features fast-flowing, mandrel-bent 2.5-inch main piping and two straight-through mufflers. The dual split rear exit, finished with 2.25-inch polished clamp-on single wall turndown tips, not only looks sporty but also contributes to the system's dyno-proven performance gains. You can expect moderate exterior sound levels and mild interior sound, creating an aggressive yet comfortable driving experience. The construction uses durable, corrosion-resistant stainless steel, manufactured with CNC precision robotic techniques to ensure a solid build. Magnaflow backs this system with a 1-year limited finish warranty and a limited lifetime construction warranty.

Thanks to extensive 3D scanning during development, this cat-back system is designed for a direct fit, making installation straightforward. It's a well-built upgrade that matches its sporty sound and appearance with real performance chops, leaving other Firebirds feeling envious at every stoplight.
