Description
The Apollo GT Series 3-Inch 409 Stainless Steel Cat-Back Exhaust System with Dual Black Tips delivers aggressive sound, proven performance, and long-lasting durability for Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. Designed for enthusiasts seeking both style and performance, this system combines premium materials with precision engineering for a true bolt-on fit.
Constructed from 3-inch mandrel-bent 409 stainless steel tubing, this cat-back exhaust provides superior strength, corrosion resistance, and optimized exhaust flow. Smooth mandrel bends reduce turbulence and restriction, enabling dyno-proven gains of up to +14 horsepower and +17 lb-ft of torque, as measured on aFe POWER’s in-house dynamometer.
The system features a high-flow 409 stainless steel muffler, tuned to produce a deep, aggressive exhaust note that unleashes all available horsepower and torque without compromising drivability.
Finishing the system are dual 4.5-inch diameter black 304 stainless steel clamp-on exhaust tips, each featuring a riveted aFe POWER logo plate for a bold, performance-inspired appearance.
Installation is straightforward and fully bolt-on, utilizing factory-style hangers to ensure precise fitment. All necessary hardware is included, requiring no cutting or modifications. This system is designed using computer-aided design (CAD) technology for high-tolerance factory fitment and is 100% MIG-welded for race-proven durability.
Proudly engineered and manufactured in Corona, California, the Apollo GT Series exhaust delivers exceptional sound, performance, and craftsmanship for demanding truck enthusiasts.
