48-34134 | AFE Power Twisted Steel 304 Stainless Steel Headers For GM Silverado/Sierra 1500 V8-5.3L/6.2L

Stainless Steel Construction:
Mandrel-bent 1-3/4" 304 stainless steel tubing improves exhaust flow for noticeable torque and horsepower gains.

Optimized Header Tube Lengths:
Optimized tube length pulse control technology delivers improved flow and performance.

Mitered Collectors:
4-to-1 mitered merge collectors decrease turbulence and increase exhaust velocity. The result is increased power and improved throttle response.

Heavy Duty Flanges:
Thick, one-piece flanges prevent warpage to ensure a leak-free seal over the life of the vehicle.

Factory Mounting Locations:
These headers retain your stock catalytic converters and factory O2 sensor locations for a direct bolt-on installation that requires no cutting or modifications.
