Flowmaster – Cat Back Exhaust System
Description
The Flowmaster Outlaw Extreme Cat Back Exhaust System (Part #817965) is designed for the Chevrolet Silverado 1500 and GMC Sierra 1500 equipped with the 5.3L engine. Built from 409 stainless steel, this system features an Outlaw series muffler delivering a deep, powerful sound and increased performance. The 3.0-inch mandrel bent tubing maximizes exhaust flow and durability. A dump-style exit positioned right after the muffler eliminates the over-axle tailpipe, improving ground clearance and departure angle for off-road use. This system produced max dyno gains of 15 HP and 21 LB/FT at the rear wheels. Bolt-on installation uses factory Hanger locations and includes all necessary hardware. Backed by Flowmaster's Lifetime Limited Warranty.
