Stainless Works FC3175-225 Three-Way Weld-On Header Collector 1-3/4" x 2-1/4"

The Stainless Works FC3175-225 is a three-way formed weld-on exhaust collector designed for custom header builds requiring a 3-into-1 configuration. Built from 304 stainless steel, this collector delivers long-lasting corrosion resistance and the structural integrity needed for high-performance and race applications. The smooth flow taper geometry minimizes turbulence as exhaust gases transition from the primary tubes into the single outlet, supporting efficient scavenging and consistent power delivery.
