Cat Back Exhaust Kit 19- GM P/U 1500 6.2L

The Flowmaster Cat Back Exhaust Kit for 2019–2021 GM Pickup 1500 6.2L delivers the signature American Thunder performance sound and improved exhaust flow that full-size truck owners seek. This stainless steel cat-back system features dual 4-inch black ceramic-coated tips with dual rear exit design and 2.5-inch diameter tubing, engineered specifically for the 6.2-liter V8 platform. Built from quality stainless construction, the kit resists corrosion and thermal stress over extended use.

The 2.5-inch tubing diameter balances scavenging efficiency with practical clearance for stock truck geometry, while the stainless steel composition handles the high exhaust temperatures produced by the 6.2L engine without degradation. The dual-exit design with ceramic-coated tips provides both functional heat management and visual presence. At 66.53 pounds, the complete kit includes all necessary components for direct bolt-on installation behind the catalytic converter. The system is designed to bolt directly to factory mounting points, requiring no frame modification or welding.

This exhaust upgrade is ideal for truck owners running modern GM full-size pickups who want audible character without sacrificing daily usability. The American Thunder series targets buyers seeking a balance between aggressive tone and street-appropriate sound levels. Fits 2019, 2020, and 2021 model year GM Silverado 1500 and Sierra 1500 trucks equipped with the 6.2L engine.

Flowmaster has positioned the American Thunder line as an accessible performance exhaust choice for domestic truck platforms, combining OEM-compatible fitment with recognizable sound signature across a range of GM powertrains. Cat-back systems like this one avoid any emissions system interference since they mount downstream of the catalytic converter.
