FEATURES:
- Designed specifically to improve exhaust flow and low-to-mid range power on 5.3L LS-based Chevrolet Silverado and GMC Sierra 1500 trucks.
- 1-3/4 in primary tubes and 2-1/2 in collectors are fully mandrel bent to maintain consistent internal diameter and reduce exhaust restriction.
- Mitered merge collectors enhance scavenging and gas velocity, contributing to more efficient cylinder evacuation and sharper throttle response.
- OE-style ball socket collector ensures a secure, vibration-resistant connection to the factory exhaust head pipe for simplified, alignment-free installation.
- Built from 16-gauge 409 stainless steel for reliable heat and corrosion resistance in daily driving and light performance applications.
- Laser-cut 3/8 in head flanges are hydraulically flattened to achieve precise surface flatness and long-term leak-free sealing under thermal cycling.
- Critical joints are brass-filled TIG welded with a golden finish, providing superior durability and resistance to thermal fatigue and cracking.
- Chrome-plated flanges and natural finish tubing offer enhanced protection against rust while maintaining a clean, OEM-upgrade look.
