Slip-On Collector 1-3/4 3-1/2 OD

The Slip-On Collector 1-3/4 3-1/2 OD from SCHOENFELD is a purpose-built exhaust header collector designed for serious engine builders and performance enthusiasts who demand maximum scavenging efficiency. This component bridges the transition between individual header tubes and your primary exhaust pipe, making it essential for any street, strip, or road race application where header design directly impacts horsepower and throttle response.

The 1-3/4 inch inlet diameter accepts standard primary tubes, while the 3-1/2 inch outlet diameter provides optimal flow characteristics for mid-range to high-RPM performance. SCHOENFELD collectors are engineered with precision tube construction that minimizes turbulence and exhaust gas reversion at critical RPM ranges. The slip-on design allows straightforward installation onto your existing primary tube work without requiring full header fabrication.

Mechanics and engine builders integrating this collector benefit most when pairing it with matching header tube sizing and a properly tuned exhaust system. The welded steel construction delivers durability under sustained high-temperature cycling, essential for consistency during extended track sessions or street driving. Its compact design ensures clearance in tight engine bay configurations common to vintage and modern performance builds.
