Upgrade your custom exhaust build with this high-quality Jones Exhaust AWHC300 header-collector reducer, designed to provide a reliable transition from a 3-inch collector to a 2.25-inch outlet while maintaining optimal flow and durability. Constructed of aluminized steel with a 3-bolt flange for easy mounting to standard headers, this reducer offers an ideal solution for adapting your exhaust to smaller-diameter piping or tailoring your system to performance or clearance needs. Its robust construction ensures longevity in demanding conditions and helps resist corrosion and heat damage over time. Whether you’re fabricating a custom exhaust from scratch or modifying an existing setup, the AWHC300 delivers value and flexibility. Please ensure your header collector is 3" with a 3-bolt flange and your downstream pipe is 2.25" OD before purchasing to ensure proper fit and performance.
