BLOX Racing Exhaust Flange - 2.5in (2-Bolt)

BLOX Racing has built a strong following in the import and sport compact community since 2003 by delivering parts that meet or exceed OEM quality standards at prices that make building accessible. Every BLOX product is designed with ISO 9001-certified manufacturing processes and subjected to rigorous testing before release, ensuring fitment and reliability that matches the performance they advertise. Popular Upgrades BLOX Racing intake manifolds and throttle bodies are popular for Honda, Acura, and other sport compact platforms, delivering improved airflow and throttle response over stock components. Suspension components including adjustable end links, sway bars, and pillow ball mounts allow precise handling tuning for street and autocross use. Engine hardware — cam gears, valve train components, and timing chain kits — rounds out the BLOX catalog for builders pushing beyond stock engine parameters. What platforms does BLOX Racing support? BLOX Racing focuses primarily on Honda, Ac...

Shop Fabrication Parts & Materials at Black Ops Auto Works for stainless steel tubing, titanium tubing, aluminum charge piping, mandrel bends, V-band clamps, flanges, merge collectors, AN fittings, PTFE hose kits, braided fuel and oil lines, heat shields, welding supplies, brackets, bungs, and hardware for building custom exhaust systems, turbo plumbing, intercooler piping, fuel systems, and engine bay routing. Start with tubing (304 or 321 stainless, titanium, or aluminum) in the right diameter and wall thickness, then add mandrel bends, flanges, V-bands, and clamps to complete the joint work. AN plumbing follows the same pattern: match dash size to horsepower target, pair the right hose (PTFE or CPE) with matching hose ends, and use adapters, bulkheads, and distribution blocks to route fuel, oil, and coolant cleanly. Shop by material (stainless, titanium, aluminum), fitting type (AN, ORB, NPT), diameter, or brand (Vibrant, Ticon, Stainless Bros, Radium, Fragola, DEI, ATP). ...

Exhaust flanges are the bolted connection points where exhaust manifolds mate to downpipes, where sections of exhaust pipe join at catalytic converters and muffler inlets, and where aftermarket headers connect to factory or custom collector sections, making flange quality and correct material specification critical for maintaining leak-free exhaust connections under the extreme temperature cycling that performance exhaust systems experience. Flange warping and gasket failures at exhaust connection points are among the most common exhaust leak sources on both stock and modified vehicles, as the thermal expansion differences between the flange material and the connected pipe cause progressive face distortion over time that breaks the gasket seal. Performance exhaust builders use thick-cut mild steel, stainless steel, or titanium flanges in precise O.D. profiles matched to their pipe diameter to ensure the clamping surface remains flat through hundreds of heat cycles.
