Hey has anyone used the JBP equal lenght header before. If so how is it and does it really give you 13-14 hp gain.

13 or 14 horsepower? For over $1,000 I would hope so, but not likely by itself.

13-14 hp from a header is possible but only a dyno can tell.

Yeah I know it possible mt friend has GS-R and he has a equal length header on his car and you can really feel the difference he had cat back also though. I was wondering if anyone had tried it and if it had been proven. I was thinking that w/ the w/ the secret cam swap and head rebuild+ this header I should get about a 30+ hp gain. Just guessing in theory though.
