Has anyone got any experience with these, or better still seen any Dyno results?
I am seriously looking at getting one of these (when the focus comes back from the panel shop!), but it's always good to seek other opinions before you leap in.
Pipercross are very reputable in the UK, and were responsible for (I think) the induction on the 2001 Focus WRC car. They are also, I understand, a quiet unit.........not interested in noisy induction systems.
UK sites go .. "yeh Pipercross" but I've never seen any soild evidence
