Muffler Mini Sprint Alum Case 1-3/4in Inlet

The Schoenfeld Muffler Mini Sprint Aluminum Case with 1-3/4 inch inlet is a compact exhaust silencer designed for mini sprint racing applications where space and weight are critical factors. Built from lightweight aluminum and finished in black paint, this muffler reduces engine noise while maintaining the performance envelope required in competitive sprint racing. The 1.75-inch inlet diameter accepts standard mini sprint exhaust piping, while the compact 3.5-inch body diameter fits tight engine bay configurations without sacrificing effective sound suppression.

Specifications underscore the engineering for weight-sensitive racing: the muffler measures 13 inches in length and 3.5 inches in diameter, outputting through a 2.125-inch outlet. At 2.55 pounds, the aluminum construction keeps overall vehicle weight minimal—a meaningful advantage in sprint racing where power-to-weight ratio directly affects acceleration and handling. The black painted finish provides corrosion resistance typical of track-used components exposed to moisture and fuel residue. This muffler integrates into existing mini sprint exhaust systems without requiring custom fabrication.

Mini sprint racers and builders sourcing OEM or replacement exhaust components will find this Schoenfeld unit addresses the balance between noise compliance and performance flow. The inlet/outlet sizing matches stock mini sprint headers and manifolds, simplifying installation. Buyers upgrading existing systems or building from scratch should verify outlet diameter compatibility with any existing downpipe or exhaust tubing before ordering.

Schoenfeld Headers has served racing exhaust markets for decades, and this Mini Sprint muffler reflects that focus on application-specific design rather than universal solutions. Track-day builders and series competitors benefit from components engineered explicitly for their platform.
