Parker Speed Billet Aluminum Dual 3" to Single 4" Merge
Parker Speed Billet Aluminum Dual 3" to Single 4" Merge

Description
Billet Aluminum Dual 3" to Single 4" Merge – Available at Tameless Performance
Combine Dual 3" Tubes in a Compact 90-Degree Package
The Billet Aluminum Dual 3" to Single 4" Merge combines two 3-inch tubes into a single 4-inch connection while making a tight 90-degree turn. Available at Tameless Performance, this compact merge is designed for custom intake and dual-downpipe exhaust systems where space is limited.
Key Features
6061 Billet Aluminum Construction
Manufactured from 6061 billet aluminum for a lightweight, strong, and fabrication-friendly component.
Dual 3" Inlets
Two inlet connections are designed to accept 3-inch aluminum tubing for custom dual-pipe systems.
Single 4" Outlet
The merged side accepts components designed for 4-inch tubing, allowing the two 3-inch paths to transition into one larger connection.
Tight-Radius 90-Degree Design
The compact shape merges both tubes while making a 90-degree turn, helping solve difficult packaging challenges.
Compact 3.5" Packaging Length
The merge occupies only 3.5 inches of space, making it well suited for tightly packaged racing and performance applications.
Thick-Wall Construction
A substantial wall thickness provides added strength and durability for demanding custom installations.
Benefits
Space-Saving Installation
The tight-radius design reduces the amount of room required to merge two tubes and redirect the combined flow.
Versatile Fabrication Options
Suitable for custom intake systems as well as dual-downpipe exhaust configurations.
Simplified Tube Routing
Combining the merge and 90-degree bend into one component can reduce the number of separate fabricated sections required.
Applications
This billet merge is suitable for custom dual-downpipe exhaust systems, intake systems, charge piping, and other fabricated assemblies requiring two 3-inch tubes to merge into one 4-inch connection.
Installation Information
Welding Required
Three-inch aluminum tubing welds to the two inlet ends. The outlet accepts a compatible flange or component designed for 4-inch tubing.
Professional Fabrication Recommended
Confirm available space, tube alignment, material compatibility, and welding requirements before installation.
