Twisted Choppers Hookah 2 Into 1 Exhaust Header Collector For Universal DIY Fabrication
The Twisted Choppers Hookah 2 Into 1 Exhaust Header Collector is the foundational component of our legendary Hookah exhaust series. Engineered for professional builders and DIY enthusiasts alike, this collector is precision-formed to allow two primary tubes to be inserted side-by-side, creating the distinct low-profile look and high-flow performance Twisted Choppers is known for. Constructed from heavy-duty 16-gauge U.S. cold-rolled steel, this collector provides the durability needed for high-heat V-twin applications.
This 8-inch long collector is a “builder’s part,” designed to be welded into custom exhaust systems for Harley-Davidson, Indian, or custom chopper frames. The 1.875-inch dual inlets are sized for standard performance primary tubes, while the large oval exit provides ample volume for exhaust scavenging and back-pressure tuning. Please note that collector covers and baffles are sold separately, allowing you to customize the final aesthetic and sound profile of your build.

Love the way these look. Can’t wait to get them fitted on my exhaust.
