The MagnaFlow Street Series Cat-Back Performance Exhaust System #15892 brings out the personality of your 6.0L 2005–2006 Pontiac GTO with MagnaFlow’s signature resonant, powerful engine tone and dyno-proven performance. Designed to improve exhaust flow and enhance both sound and appearance, this system gives your GTO the aggressive edge it deserves.
The fast-flowing 2.5-inch mandrel-bent main piping channels exhaust gases through two straight-through mufflers before exiting in a Dual Split Rear configuration with 4-inch polished welded-on double wall angle cut folded edge tips. The result is a balanced sound profile delivering moderate exterior and mild interior sound levels, sporty yet refined for everyday driving.
Exhaust kit #15892 features a cat-back layout that replaces your vehicle’s factory exhaust components from near the catalytic converter on back. Extensive 3D scanning during development ensures a precise direct-fit design for straightforward installation. Manufactured from durable, corrosion-resistant stainless steel using advanced CNC precision robotic techniques, this system is backed by MagnaFlow’s 1-year limited finish warranty and limited lifetime construction warranty.
