BBK 09-24 RAM 1500 HEMI 5.7L 3in Cat Back Y-Pipe Adapter (Use w/ PN 19501)

Introducing the 2009-2018 RAM 1500 HEMI 5.7L 3" Adapter for 19501 Y Pipe — the precision-fit solution designed to maximize flow and performance when upgrading your exhaust system. Built for the 2009-2018 RAM 1500 with a HEMI 5.7L, this 3" adapter is tailored to connect BBK long tube headers with the 19501 Y pipe, delivering a smoother, more efficient path for exhaust gases and unlocking real-world gains in throttle response and feel.

Why this adapter makes a difference

• Designed for BBK long tube headers — use only with BBK Long Tube Headers for RAM (Part #1950 or #19500) paired with mid-pipe 19501 to achieve the best match and fit.
• 3" CNC mandrel-bent stainless steel tubing ensures a smooth, unrestricted exhaust path, reducing bottlenecks and preserving high-flow benefits from your headers.
• Easy installation and secure fit — the adapter can be welded or clamped to the BBK mid-pipe to connect with the OE or aftermarket cat-back exhaust. Some adjustments may be required for a perfect fit, but the process remains straightforward for most hobbyist installers.
• Enhanced performance and sound — when paired with BBK headers, this adapter helps the engine expel exhaust gases more efficiently, translating to sharper throttle response, more perceived power, and a deeper, more authoritative exhaust tone.

Who this is for

• 2009–2018 Dodge RAM 1500 HEMI 5.7L owners upgrading to BBK long tube headers
• DIY enthusiasts upgrading from stock or aftermarket 3" cat-back systems who want a clean, reliable path from headers to the cat-back
• Vehicle builders seeking a durable, heat-tolerant mid-pipe adapter designed to endure high-performance usage

Key fitment and usage notes

• Compatibility — not compatible with OEM manifolds or BBK shorty headers. For use ONLY with BBK Long Tube Headers for RAM (Part #1950 or #19500) with mid-pipe 19501.
• California notice — this part is NOT CARB approved and cannot be used on emission-controlled vehicles in California. California Prop 65 warning applies; do not ship to California residents for on-road use.
• Installation considerations — ensure proper alignment with the 19501 Y pipe and cat-back exhaust. While the adapter is designed for straightforward mounting, some configurations may require minor modifications for a perfect fit.
• What you gain — improved exhaust flow translates to improved throttle response and a more engaging driving experience, especially when paired with BBK headers and the appropriate mid-pipe.

Technical highlights

• 3" (78 mm) diameter mandrel-bent stainless steel construction for optimal flow
• Part #19504 adapter specifically designed for the 19501 Y pipe configuration
• Durable and heat-resistant build to withstand high-performance use
• Emissions note — not approved for California emissions systems; plan accordingly for your build and location

To proceed with the upgrade, pair this adapter with BBK long tube headers (Part #1950 or #19500) and mid-pipe 19501, then connect to your cat-back exhaust. The result is a cohesive, high-flow system that helps your 2009 RAM 1500 HEMI 5.7L breathe easier, delivering a more engaging driving experience and a listening profile that mirrors the performance gains.
