Gains to be had from panel filter and back box?
 

Hi guys,

I have a uk boxster 2.7 so no cats in the manifold,

Im going to give it a full service this weekend and im thinking of putting in a high flow panel filter i.e BMC's one, and at the same time getting one of the dansk sport back box's with twin tips like the boxster s, my question is has any one done any dyno work to see what a panel filter and back box does? And is it worth it for a little more shout when you stamp on the loud pedal?

Cheers
