The Flowmaster Outlaw direct-fit muffler, part number 817633, is designed for 2009-2024 RAM 1500 trucks with the 5.7L Hemi, factory dual tailpipes, and the Classic body style. It fits both two-wheel-drive and four-wheel-drive models across all wheelbases, delivering a deep, powerful, and aggressive exhaust note inside and outside the truck. This system does not fit the 2019-2024 new body RAM 1500.
Built for drivers who want a bold performance sound, this Flowmaster system uses a 3-inch mandrel-bent inlet tube that flows into a specially designed Outlaw muffler before exiting through dual 2.5-inch outlet pipes. The outlets connect directly to the factory dual tailpipes, providing a clean installation while retaining the original tailpipe configuration. Race-proven Outlaw muffler technology and dyno-tuned design help support strong exhaust flow and responsive performance.
The stainless steel construction provides durability for long-term use, while the direct bolt-on design uses the factory hanger locations for a straightforward installation at home. All required parts, mounting hardware, and easy-to-follow instructions are included. The Flowmaster 817633 is backed by a Lifetime Limited Warranty and delivers the quality, fit, and aggressive sound expected from Flowmaster exhaust components.
