We tested these headers back to back against ebay headers. Testing was done on the same day, same dyno, same car, same conditions! This is a true back to back test!
We have not tested our headers against stock exhaust manifolds, that test would show very large gains.
First car 2004 Maxima w 2010 Maxima engine, 350z ecu stock cams. showed gains in midrange and top end. 10hp and 4ftlbs tq.
Second car 2006 Altima SER with 2010 Maxima engine with JWT Cams showed gains above 4000 rpm 14hp and 10 ftlbs tq.
