Stainless Works RAM09CBY-S Cat-Back Exhaust System with Y-Pipe and Dual S-Tube Turbo Mufflers

The Stainless Works RAM09CBY-S is a premium 3-inch cat-back exhaust system engineered for the Dodge Ram 1500 5.7L HEMI Quad Cab and Crew Cab. Constructed from corrosion-resistant 304 stainless steel and fully TIG-welded, this system delivers a significant upgrade in exhaust flow, sound, and long-term durability over the factory setup.

Key Features:

• 3-inch CNC mandrel-bent tubing throughout for unrestricted exhaust flow and no pipe buckling
• Y-pipe configuration routes exhaust from a single factory connection point to dual rear exits
• Dual turbo S-tube mufflers — the most aggressive sound option in the Stainless Works lineup, delivering a deep, throaty rumble at cruise and a powerful roar under hard acceleration
• Dual 3-inch polished double-wall slash-cut conical tips exit under the rear bumper on both sides for a bold, clean appearance
• Factory Connect design — bolts directly to the OEM exhaust flange with no cutting required
• 304 stainless steel construction will not red-rust like lower-grade 409 stainless alternatives
• 3/8-inch thick flanges for a strong, leak-free seal
• Uses factory exhaust hangers for straightforward, bolt-on installation
• Proudly made in the USA and backed by a limited lifetime warranty on materials and workmanship

The turbo S-tube muffler design is Stainless Works' loudest muffler option and is engineered for maximum exhaust flow. All necessary hardware is included for a complete, install-ready experience. For those seeking even greater performance, this system is also compatible with Stainless Works long-tube headers via the Performance Connect variant.
