BLOX Racing Max-Flo [commonly referred to as ‘big tube’] exhaust headers are specifically intended for Honda B-series with high compression 1.8L set-ups and other builds between 2.0L-2.2L in displacement. Max-Flo exhaust headers are 2-piece and feature a 4-2-2-1 (Tri-Y) design using innovative stepped exhaust tubing, which are larger when compared to its Hi-Flo little brother.
T304 is used to construct these stainless steel headers, including T304 cylinder head and collector flanges. All headers are expertly TIG-welded to ensure durability and reliability. Spent exhaust gases exit through true 2.5" exhaust collectors.
BLOX Racing Max-Flo headers are designed to widen midrange power and take advantage of peak horsepower.
