WARNING: Cancer and Reproductive Harm www.P65Warnings.ca.gov

BLOX Racing Hi-Flo [commonly referred to as 'small tube'] exhaust headers are specifically intended for Honda B-series engines between 1.6L-1.9L in displacement. Hi-Flo exhaust headers are 2-piece and feature a 4-2-1 (Tri-Y) design using innovative stepped exhaust tubing.

16-gauge T304 is used to construct these high performance, stainless steel headers, including T304 cylinder head and collector flanges. All headers are expertly TIG-welded to ensure durability and reliability each time you start up your engine. Spent exhaust gases exit through true 2.5" exhaust collectors.

BLOX Racing Hi-Flo headers are designed to widen midrange power and take advantage of peak horsepower.
