Slip-On Collectors 2-1/4in x 4-1/2in (Pair)

The Hedman Slip-On Collectors 2-1/4in x 4-1/2in Pair (Model 14146) is an essential component for custom exhaust builders and engine modification enthusiasts. These collectors are designed to enhance scavenging and flow characteristics, making them ideal for high-performance builds. Whether you're working on a street rod, restoring a classic muscle car, or optimizing an engine swap, these collectors play a crucial role in improving horsepower delivery and exhaust gas velocity.

Constructed from durable steel with a natural (unpainted) finish, the collectors feature a primary tube diameter of 2-1/4 inches and a 4-1/2 inch outlet. This design is optimized for mid-range to high-RPM power bands typical of V8 and larger displacement engines. The slip-on design allows for flexible fitment in tight engine compartments and simplifies installation compared to welded alternatives.

Serious fabricators, hot rod builders, and performance mechanics will appreciate the balance of structural integrity and practical weight management these collectors offer. The natural steel finish requires proper heat shielding and finishing to prevent rust in high-temperature exhaust environments, but it provides an excellent foundation for further coatings. These collectors are a must-have for anyone looking to enhance their vehicle's exhaust system.
