10-17 GM P/U 1500 5.3L Cat Back Exhaust Kit

The PYPES Performance Exhaust 10-17 GM P/U 1500 5.3L cat back exhaust kit is engineered for truck owners and performance enthusiasts seeking measurable gains in horsepower, torque, and throttle response. This cat-back system replaces the restrictive factory exhaust from the catalytic converter rearward, making it an ideal upgrade for stock or lightly modified GM full-size trucks running the LS-series 5.3-liter engine. Whether you're prioritizing highway cruising comfort or occasional spirited driving, this bolt-on solution delivers noticeable improvements without requiring engine tuning or internal modifications.

Built from premium stainless steel in a natural finish, the Violator-series kit features 2.5-inch intermediate pipes that balance scavenging efficiency with street-friendly sound levels, coupled with a larger 3-inch polished stainless tip for visual impact and unrestricted exhaust flow. The intermediate pipe diameter and tip sizing are sized specifically for the 5.3L displacement and power band characteristics of the GM LS platform, optimizing back-pressure to enhance mid-range torque while reducing rasp at cruise speeds. Stainless construction resists rust and corrosion through harsh winters and road salt exposure, ensuring long-term durability and maintaining appearance with minimal maintenance.

Owners of 2010–2017 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks will find straightforward bolt-on installation using factory mounting points; no cutting, welding, or welding experience required. This compatibility makes it an accessible first modification for truck builders transitioning from stock to performance platforms. The 54-pound system arrives well-packaged and ships ready for same-day or weekend installation in any home garage or professional shop, making it a practical choice for buyers seeking both performance and value.
