Hi,

JanSpeed (pronounced YahnSpeed) is a well respected aftermarket supplier to Porsche and Audi.

I question their claimed hp increase though. They mention a Sports Performance Pkg., but don't describe it. The headers/Cats go by another name, so that may not be all there is to it. Also, their Dyno runs are probably using european, more highly refined fuel...

Happy Motoring!... Jim'99
