i dont believe they make equal length headers for our cars. they are just lucky to get them to fit, let alone be the same length
the only short header i've heard make any hp was the jba ones. like 8-12rwhp. the longtubes typically get 10-15rwhp. both are a real pain to install. the long tubes are worth the sound alone
