Description
Overview
The Flowmaster® Outlaw Exhaust System Kit is a complete cat-back upgrade engineered for 1988–1993 Chevrolet and GMC 1500/2500 LD trucks equipped with the 5.7-liter (350) engine. Built to deliver a bold, unmistakable presence, this Outlaw Series exhaust system pairs aggressive sound with real performance gains, making it a standout choice for owners who want their classic GM truck to look and sound as strong as it runs.
Constructed from durable 409 stainless steel tubing and fully mandrel bent, this performance exhaust promotes smoother, freer-flowing exhaust gases from the muffler back. Mandrel-bent tubing preserves a consistent inner diameter through every bend, so your car exhaust breathes better and helps the 350 make the most of its power. Whether you’re chasing a deeper tone or a cleaner, higher-flowing exhaust pipe path, this catback exhaust is designed to do both.
Sound & Tips
At the heart of the system is an Outlaw Series muffler tuned for an aggressive sound level and maximum performance. The kit finishes with dual 4.5-inch black ceramic-coated tips featuring an embossed tip logo. Best of all, you choose how it exits: configure the dual tail pipes to route dual out the rear or dual out the side to match your truck’s stance and personality.
