Exhaust Collector

Exhaust Collectors & Merge Collectors

Exhaust collectors merge multiple primary exhaust tubes into a single outlet, forming the transition between individual header runners and the rest of the exhaust system. Collector design directly affects exhaust scavenging, backpressure, and power delivery — making the right collector an important part of any header or custom exhaust build.

OneFastShop carries exhaust collectors including 4-into-1 merge collectors, 4-into-2-into-1 stepped collectors, slip-fit and flanged collectors, stainless steel and mild steel construction, and collectors in popular primary tube and outlet sizes for header fabrication, custom exhaust builds, and turbo manifold projects.

Every exhaust collector at OneFastShop ships brand-new and ready to weld or clamp. Whether you're fabricating a custom header, replacing a worn collector on an existing set of headers, or building a turbo manifold, OneFastShop has the collector. Shop the full exhaust collectors collection today.
