well i had/have the oil consumption problem.

the clear bra the dealer installed was starting to come off a bit
and
the coating on the grill was flaking

new grill installed
clear bra fixed

oil consumption monitoring underway

i asked the dealer about after market exhaust and intake and he said it was no problem as far as warranty stuff went. I had put the stock intake and exhaust back on for the service just in case because of the oil consumption.

I did notice a significant difference in the way the car felt going from the stillen items back to oem.

the loaner car i had, a g35 sedan with 20,000 miles on it was a real POS. that thing creaked worse than any car i have EVER been in. it was unreal.

ok, that is all. i will report more in 1000 miles after i visit the dealer for the oil consumption test
