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.

We are a small Maxima/Altima performance focused shop. Manufacturing these headers in house, this first production run lead times will vary depending on the number of orders.
