I found with the CP-E CAI (complete with dry flow filter) was very loud and almost a tinny sound. Kind of like pressurised air through aluminium pipework kind-of-tinny-sound. I got rid of the standard dry flow and attached a K&N 3" hi-flow pod. The result is more of a base note, much deeper and also the performance I felt was slightly more aggressive at high rpm. This is most likely due to the less resistance (oiled filter + increased surface area).
I think there is potential for significant weight reduction in the MPS6 (also the 3) A CF hood, light weight rims alone has got to knock off around ~80-100kgs or there about...my mates EVO 8 hood is so light in comparison to the 6. Although still quick off the line the AWD MPS6 could be nuts, with a few well placed mods and weight reduction.

With great power comes great fuel consumption...

The MPS6 bonnet weight is contributed to by the combined weight of the soundproofing and the plastic ducting to the OEM TMIC. But with my CS_FMIC, I still have to keep it as the ducting now serves to ram air into the "TMAF" (top-mounted air filter). It also rams in flies, moths, grasshoppers, butterflies and other assorted small wildlife, but its easily cleaned removed with a vacuum cleaner. Makes me wonder if a nice open-weave grating across the intakes to catch the little guys might be worthwhile.
