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

The SCHOENFELD Slip-On Collector 1-5/8in x 3in (SO63041) is a specialized exhaust header collector designed for street and performance applications that require efficient primary-to-outlet transitions. 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.

Constructed from steel with a black paint finish, this collector is designed to fit within 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 wide 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.

This collector is ideal for 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 both DIY builders and professional shops alike, facilitating easy integration with existing primary pipes or direct header connections.
