Description
Overview
The Flowmaster® Outlaw Exhaust System Kit is a complete cat-back exhaust system engineered for 1996-1999 GM 1500 trucks equipped with the 5.7-liter engine. Designed to bolt on where your factory system ends, this Flowmaster Outlaw catback exhaust delivers a serious upgrade in flow, tone, and appearance for Chevrolet and GMC pickups. If you’ve been searching to shop for exhaust that combines proven engineering with easy home installation, this performance exhaust system checks every box.
Built from durable 409 stainless steel tubing and fully mandrel bent, this exhaust pipe design promotes smoother exhaust gas flow for improved performance. The 16-gauge, 3.00-inch inlet piping wears a clean silver finish, while the heart of the system, a Super 10 Series muffler, produces a bold sound level that lands squarely in the aggressive-to-moderate range. Whether you want a rowdy note under throttle or a manageable tone at cruise, this exhaust system was tuned to make your 5.7 come alive.
Key Benefits
This complete car exhaust kit is finished with dual 4.5-inch black ceramic coated tips featuring an embossed Flowmaster logo. The tips can be configured to exit dual out the rear or dual out the side, giving you the flexibility to set up the look and stance you want. The black-coated muffler and blacked-out tips pair with the silver mandrel-bent piping for a purposeful, factory-plus appearance.
