3in To 3in Collector w/O2 Sensor Bung 3 Bolt

The HEDMAN 3in To 3in Collector w/O2 Sensor Bung 3 Bolt is a precision exhaust manifold collector specifically designed for builders and mechanics who are upgrading stock or modified engine packages with aftermarket headers or primary piping. This component acts as the consolidation point where multiple primary tubes merge into a single 3-inch outlet, enhancing exhaust flow while allowing for oxygen sensor monitoring.

Constructed with durability and flow efficiency in mind, this collector features a welded 3-inch inlet-to-outlet design that minimizes turbulence and back-pressure loss during the critical transition from primary tubes to the exhaust system. The integrated O2 sensor bung accommodates standard wideband or narrow-band oxygen sensors, enabling real-time air-fuel ratio monitoring without the need for additional drilling or aftermarket bungs.

Ideal for street machines, weekend racers, or high-performance daily drivers, this collector is essential for proper exhaust scavenging and engine management. The three-bolt flange connection ensures a secure and repeatable mounting interface that resists vibration and thermal cycling, making it a reliable choice for high-heat engine compartments.
