Description
Our 4-into-1 full race step-header. The primary tubes of this header start out at 1 5/8″ diameter and increase to 1 3/4″ – this ‘step’ helps scavenge the exhaust gases while maintaining high gas velocity – the result is the midrange torque of 1 5/8″ header with the high end of a 1 3/4″ header. These have a 3″ collector.
This header was designed for race engines with more than 175HP. Our customers have reported dyno results which show these are absolutely the best performing M10 headers on the market. Photo shows header with optional ceramic coating.
These headers are proudly made right here in Southern California.
Ceramic coating has a 2 week lead time.
Note 1: These do NOT fit right hand drive cars.(Australia, UK, Etc.)
Note 2: The headers are made from mild steel. To prevent rust and corrosion, consider either ceramic coating (see main photo above) or using high-temp paint. Uncoated headers are typically painted black for protection during shipping, this black paint will burn off once headers are installed.
