Can anyone explain the difference between the 04/05 intake and exhaust...
What is the intake flap and where is it. Were the exhaust valves taken off the 05's? The valves were for opening different channels @ different RPM's for varying flow, I'm assuming?

Minor differences. The Exhaust no longer has the "flaps" that change exhaust note. Not sure what changes happened with the intake, but I hear that there were some minor ones.

Re: Check here..........
Real nice illustration. Thanks. It seems like it should be the other way around, w/ the flap opening under harder acceleration. So the 05 has d/c'd the flap; does that mean the system is more open in all conditions now?
