there was a header review in a magazine i think it was D SPort, anyways they tested like 10 different headers there were all tested on a b16 delsol who baseline tested 131 hp. Well this hytech header 4-1 desing put out like 189 hp, thats a 58 hp increase, i was like dam. the only downside is its 1200 dollar price.
anyone here got this header.

 

58hp increase from a header ?
You must have read something wrong...
If this was the case everyone would run $1200 headers.

Read part 2 that was in TPR magazine where they discuss what the header put out, part 1 was also in TPR that large gain was mianly attributed to a dyno error

Anyways regardless of that look at the other test on the dyno jet and you will see, point being john makes great headers that have great quality The ehader that was tested was his "production" header that retials for around 800? correct if im wrong
