Description
Street stock racing demands exhaust systems that flow efficiently without sacrificing durability, and these Schoenfeld headers deliver exactly that through optimized primary tube sizing and collector design. The 1-3/4″ primary tubes are tuned specifically for Small Block Chevy power curves, reducing back-pressure while the 3″ collector transitions exhaust gases smoothly into your exhaust system. Built from quality steel and finished in black, these headers are engineered to withstand repeated heat cycles and hard racing while helping you extract every available horsepower.
