Weld On Merge Collectors

304 stainless steel weld-on merge collectors are the heart of any high-performance header build. Designed to smoothly merge individual header primaries into a single outlet, our collectors are hand built to withstand any application.

Available in 2 into 1, 3 into 1, and 4 into 1 configurations across a wide range of inlet and outlet sizes, these collectors are precision-formed for consistent fitment and a clean weld-ready finish. Whether you're building a race header, a swap setup, or a custom exhaust system from scratch, our collectors are up to the task.
