Independently dyno and track tested by Bader
Built Racing! Our header made its debut literally off to the races on Justin's
BBR built 2007 STI before ever hitting the dyno! Put through the paces on the
drag strip running a handful of low 9 sec passes with a stock location DOS100
turbocharger running a new PB of 9.14 @ 154mph solidifying real world drag
strip testing as a success! Josh @ BBR was able to throw it on the dyno a few
days later laying down an impressive 733whp and 629wtq @ 30psi picking up 15whp
and 21wtq at peak power over the previous header in back-to-back testing showing impressive gains throughout the powerband!!
Our header also out spooled it by a few hundred rpm making an additional 46whp
and 57wtq midrange power!!

Important Note: This header design is equal length for optimal flow therefor using this header will eliminate the EJ's boxer rumble.
