been reading all the posts about cai and would appreciate any feedback.not sure if i want to add a cai(pop charger)to my car.have wsp y pipe and high flow cat.Had hole in my resonator so local mufflr shop cut it out and relaced wth straight pipe.have a focuz muffler,car sounds pretty good really,a little loud but not ridiculous.dont know if i want any more noise that a cai would have under throttle.is a k&n drop in worth the investmnt,is it that much better than stock.Also this may be a stupid question but if i was to drill out the top of my air filter box with 1/2" holes all over than placed a piece of fine screen inside to prevent any dirt from getting in would that do anything to increase air flow????

 

Any aftermarket intake (be it Pop charger OR CAI) that removes the resonator is going to sound loud under WOT. I dont have an aftermarket exhaust per se, and so at redline my intake is making more noise than my exhaust.

There's a resonator box for your intake too.

 

two resonators involved with the intake actually
