Got my Dinan Exhaust and Stage3 installed. Just love the car, but as mentioned here think it may take a few days for the Stage 3 to set in ( i already see some power increase ).

On the exhaust, my first impression was WOW, it sounds great and it completes the package with all that power. I will make some videos and post it soon. Just one thing I am not still settled on. I hear drone between 1500-2000 rpm, this gets worse as it gets closer to 2000 rpm and then dissappears.

Should I give it a few days or go back to the dealer to see if they can tweak it ...? Any advise guys?
