    BLOX Racing titanium headers are now available for Honda B-series applications.  BLOX Racing is extremely proud to be the 1stcompany to offer production titanium headers.

    This titanium exhaust header is the twin to our existing Hi-Flo design and still offers the same benefits and gains of stepped exhaust tubing by maximizing exhaust flow, widening the powerband and increasing horsepower and torque. 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 4-2-2-1 (Tri-Y) design using innovative stepped exhaust tubing.

    Even though these titanium headers are based on existing designs, that’s where any similarities end. Each header is constructed out of 100% Grade 1 titanium, the purest form, which offers exceedingly greater amounts of attributes for, particularly, exhaust components and other high performance and racing products.

    Each titanium header is handmade and hand TIG-welded. Considering, the expert skill and craftsmanship that goes into each unit ensures that each header is constructed the same way, each and every time. This consistency in production allows for proper fitment and seal against exhaust leaks.

    Compared to each of its T304 twin, the titanium version is 58% lighter!  58% lighter!

    Stainless Steel 304

    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 4-2-2-1 (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.
