Description
If you’re running a 1999-2006 GM full-size pickup with the regular cab and short bed, this cat-back system delivers the flow and sound your truck deserves without the complexity of a full custom build. The American Thunder design optimizes exhaust scavenging through a mandrel-bent 2.5-inch diameter pipe, resulting in measurable gains in throttle response and engine efficiency. At this price point, you’re getting bolt-on simplicity with durable aluminized steel construction that handles years of daily driving and weekend duty.
