Slip-On Collector 1-5/8in x 3in

The SCHOENFELD Slip-On Collector 1-5/8in x 3in (SO63041) is a purpose-built exhaust header collector designed for street and performance applications requiring efficient primary-to-outlet transition. This slip-on collector consolidates four 1.625-inch primary tubes into a seamless 3-inch outlet, engineered to maximize scavenging efficiency while minimizing turbulence at the collector entry point. Constructed from steel with black paint finish, the 8-inch length accommodates tight engine bay configurations common in modern performance builds.

The 1.625-inch primary tube diameter matches standard small-block header sizing, making this collector compatible with a broad range of aftermarket header systems. The 3-inch outlet diameter provides adequate flow capacity for naturally aspirated engines in the 400–500 hp range without excessive backpressure. The slip-on design eliminates welding requirements, allowing straightforward integration with existing primary pipes or direct header connection. Black powder-coat finish resists corrosion and oxidation typical in underhood environments, extending service life across multiple seasons of driving.

This collector suits builders prioritizing simplicity and cost-effectiveness in mid-level performance exhaust systems. It works well for carbureted engines, fuel-injected V8s, and applications where a compact collector footprint is essential. The straightforward slip-on construction appeals to DIY builders and professional shops alike, offering reliable primary-to-outlet consolidation without complex fabrication.

SCHOENFELD is recognized for mid-range exhaust components targeting street performance and hot rod markets. The SO63041 represents a practical balance between flow capability and installation convenience, making it a solid choice for builders seeking functional header plumbing without premium pricing.
