I would like to return to some sort of standard set up with a air box. The "Darth Vader" noises are annoying me now. I have read in some posts that Flea himself has said the SIP is not needed anymore. Has anybody done any back to back tests, either on a dyno or on the road, standard intake versus modded ? With the standard airbox I appreciate it will need an aftermarket filter( K & N, ITG etc) and perhaps a bigger trumpet. Thoughts anybody ? Flea ? Sean Enjoying Coop ownership, second time round .

Topchoc Unregistered T	I have been doing performance mods one by one gauging the gains prior to this morning i have done 200 cell sport cat, gtec1 chip, turbo revs fmic all with significant gains ,and this morning a sip with a k&n filter and i feel there is a noticeable difference on acceleration Even if its a 1 bhp gain its worth it for the noise alone
