Great info. Very straightforward. Is this in the uberthread? It should be.
I installed mine last night. Did not need Rhino Ramps or any type of lift. Also did not need to remove the undertray; just the rear diffuser.
The PB Blaster was very helpful as it was still a bitch to get the old exhaust out of there. I just ended up wiggling it up and down and it eventually came out. You aren't kidding that stock muffler is HUGE!
Only problem I encountered believe or not was reinstalling one of the hanger mounts on the passenger side, as the holes weren't matching up.

Of course I was reinstalling it at night in my apt. complex garage w very poor lighting. I also notice some burning smell, which I assume is burnoff of the PB blaster.
Otherwise it now sounds like a beast

much better that the "fartcan" stock exhaust. Thanks Matt for the exhaust.
