Description
The Apollo GT Series 3-Inch 409 Stainless Steel Cat-Back Exhaust System with Dual Polished Tips is engineered to deliver aggressive sound, dyno-proven performance gains, and long-lasting durability for select Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. Designed for enthusiasts who want both performance and style, this system combines premium materials with precision engineering for an OEM-quality, bolt-on fit.
Constructed from 3-inch mandrel-bent 409 stainless steel tubing, the Apollo GT cat-back exhaust provides superior corrosion resistance, strength, and optimized exhaust flow. Smooth mandrel bends reduce turbulence, enabling up to +14 horsepower and +17 lb-ft of torque, as verified on aFe POWER’s in-house dyno.
The system includes a high-flow 409 stainless steel muffler, tuned to produce a bold, aggressive exhaust note that enhances throttle response while maintaining everyday drivability.
The exhaust is finished with dual 4.5-inch polished 304 stainless steel clamp-on tips, each featuring a riveted aFe POWER logo plate for a refined, performance-inspired look.
Installation is completely bolt-on, utilizing factory-style hangers for a secure and precise fit. All necessary hardware is included, requiring no cutting or modifications. Designed using computer-aided design (CAD) technology, this exhaust ensures high-tolerance fitment and is 100% MIG-welded for race-proven durability.
Proudly engineered and manufactured in Corona, California, the Apollo GT Series exhaust system delivers exceptional craftsmanship, aggressive sound, and proven performance.
