Flowmaster's® Signature Series Cat-back exhaust system is designed specifically for the 2019-2024, 2026 RAM truck (new body) with 5.7L Hemi and factory dual exhaust. Features include full brushed 304 stainless steel construction, large 3.00-inch flanged inlet pipe flowing in the single inlet/dual outlet Signature Series "straight-through" muffler for great sound and maximum performance. This premium exhaust system is TIG welded for a stronger, more precise weld that looks as good as this system sounds. The dual 2.50-inch mandrel bent tailpipes clear the factory hitch and spare tire and exit out through the factory rear bumper cutouts with large 4.50-inch diameter PVD coated black chrome 304S stainless steel tips giving your RAM that custom look that goes hand in hand with that deep performance Signature Series sound. Max dyno gains of 13 hp and 13 lb-ft at the rear wheels. The system uses all the factory hanger locations and connections for an easy installation that you can do at home. Includes installation instructions and all necessary hardware. Note: This system fits all wheelbases, both two and four wheel drive models along with all cab and bed configurations.
- • Signature Series muffler offers an aggressive to moderate performance tone and increased performance over the stock system.
- • TIG welding offers a more precise weld, better heat control and high-end appearance compared to MIG welding.
- • Brushed 304 stainless steel offers maximum corrosion resistance for a cleaner and more high-end appearance.

- • Installer friendly design allows for an at home installation.
- • Increased power and torque over the stock exhaust system.
- • Black chrome tips offer a stylish upscale look.
- • Dyno proven performance gains you can feel.

Manufacturer's Warranty — Flowmaster

Manufacturer's Warranty — Flowmaster
Flowmaster warranty is tiered by material and product line. Lifetime Limited Warranty — stainless steel mufflers (FlowFX series excepted), all stainless steel exhaust systems (FlowFX included), stainless steel pipes, air intake kits and oiled-type filters (cleaning kits excepted), and other stainless steel exhaust accessories (exhaust tips and racing products excepted); this runs for the life of the original vehicle the part was installed on. Three (3) years — aluminized steel mufflers, exhaust systems and pipes, all exhaust tips, other non-race exhaust accessories, and commercial-vehicle applications of aluminized or stainless products. Two (2) years — Delta Force dry air intake filter elements. One (1) year — FlowFX series mufflers, Elite Series headers, and electronic components such as Delta Boost modules. Catalytic converters sold under the Flowmaster brand are excluded from this warranty. Coverage runs from the date of original purchase, to the original purchaser only, and only while the part remains on the vehicle it was originally installed on. Header coverage does not extend to damage caused by exhaust insulating wrap and is void if the header was fitted to a new or rebuilt engine during the initial break-in period. Sound-absorbing material inside “straight-through” mufflers degrades over time; Flowmaster treats that as normal wear, not a material defect. Also excluded: interior and exterior sound levels, cosmetic issues such as coatings and material discoloration, installation on a racing vehicle, improper installation or installation contrary to Flowmaster instructions, alteration, misuse, repair, accident, collision, undercarriage road impact or debris, and willful or negligent acts. To claim, the original purchaser returns the product either to the original retailer or directly to Flowmaster — a Returned Material Authorization (RMA) number must be obtained from Flowmaster first if returning to them — with proof of purchase showing place, price, product and date. Flowmaster's remedy is exchange for the same part number or refund of the purchase price at its option; installation, labor, towing and shipping costs are not covered.
Warranty terms are set by the manufacturer and may change. Full details and claims are handled directly by Flowmaster. Contact us if you need help with a warranty claim.
