RE: Installing Magnaflow Exhaust this weekend.
I installed Magnaflows the 2nd day I owned my '09 R/T.
It does drone quite a bit at around the 2,000 RPM mark.
But............the idle is awesome, the full throttle is better than anything else I have heard.
The 2,000 RPM drone is annoying - get used to it.
