I got the DerpPipe in. It would have been a 20 minute job easy, if it weren't for that infamous hidden bolt. Ended up taking an hour. For anyone looking to do this install. Make your life easier by disconnecting the charge hose that comes right off the compressor and move it out of the way, then you can get to the "hidden bolt" with ease, with a deep socket 10mm on a 1/4" drive ratchet.
Fired it up, and it is LOUD. I haven't gone out for a spin, cuz I got to clean up and get ready for class. Also while I had it jacked up, I took out an additional 1/4" of ride height on the Pedder's in the front. Im gonna need to modify the sheet metal of the fender well soon. I don't mind rubbing the plastic well, but the sheet metal seems might damage my new tires.
Now Hardly Functional.
