Speedwerx Performance Exhaust Headers are proven to be better than the competition on the dyno and on the track! You can rely on our 30+ years of experience of manufacturing exhaust- built by racers, for racers. Unlike most of the competition, we do not take a one size fits all mass production approach and all headers are hand built to order so you will get a superior quality product that is tailored to the engine specifications for the best power and performance within your sanction or series rules. We specialize in Tri-Y and 4-into-1 design headers that add serious torque and horsepower with our three stage stepped equal length primary tubes and machined merge collectors or precision fit standard collectors, but we also have custom designs and fits available to meet the needs of any engine builder, racer, or sanction/track class rules. While the other major brands MIG weld all of the mild steel and some of the stainless steel headers, all of our headers have TIG welded tube joints whether they are mild steel or stainless steel, and the stainless steel headers are purge welded for the smoothest finish inside. The tube to flange joints are fully welded on the inside and then are contour blended by hand into the tube- the end result looks much like a ported cylinder head for a smooth transition from the exhaust port into the header with minimal disruption to the exhaust flow. We pride ourselves on the fit and finish too- all the tubes are hand cut and buffed, and then assembled in a jig so not only do you get the best performing product but you get the best looking product and hassle-free installation as well. Last but not least, all Speedwerx Performance Exhaust Headers are 100% Made in the USA!
