3in Collector 2-1/4in Outlet

The 3in Collector 2-1/4in Outlet reducer from Hedman (Model 16010) is a precision exhaust transition component designed for custom engine builders and performance mechanics who require reliable step-down flow control. This reducer is essential for turbo systems, header installations, and high-performance exhaust builds where a smooth transition in tube diameter is critical to prevent turbulence and backpressure spikes.

Constructed from heavy-duty mandrel-bent tubing, the 3in Collector 2-1/4in Outlet reducer features precision-engineered internal geometry that minimizes flow disruption during the transition from larger to smaller diameter. The stepped design allows exhaust gases to taper gradually, reducing turbulence that could create negative pressure waves and restrict scavenging efficiency. Weighing just 2.45 pounds and measuring 5.9 x 5.1 x 8.2 inches, this compact component integrates seamlessly into tight engine bay configurations without compromising durability or long-term reliability.

Experienced fabricators and street/strip builders choose this reducer when matching larger-diameter headers or collectors to smaller muffler inlet tubes, downpipes, or secondary piping. Installation is straightforward for both welding and clamp-on applications, and the proven Hedman construction ensures years of service without warping or internal corrosion. Whether you're building a custom exhaust system or upgrading your vehicle's performance, this reducer is a reliable choice for optimal exhaust flow.
