BMW STAGE 2: Street and Track Performance Step Header for 2002

Performance/Race.  Our exclusive 4-into-1 step header. The primary tubes of this regular steel header are 1.5" diameter and increase to 1.625". This 'step' helps scavenge the exhaust gases while maintaining high gas velocity - the result is the strong midrange torque of a 1.5" pipe header with the high end of a 1.625" header. They're great for performance street cars and for race cars up to about 175HP (SCCA ITB and ITA cars, VARA, etc.). These are top-quality headers designed specifically for the BMW M10 engine - dyno tests have shown they out-perform every other header on the market. Photos shows aluminized ceramic coating option. For street cars with a stock exhaust or our stainless steel exhaust system, order a 2.5" header Collector Adapter.

Made in the USA.
