Just got back from a trip to Detroit Lake. In the time since then, I've changed my oil and gutted my cat. The increase in power is very noticeable, and so is the increase in exhaust noise. I'll post up a video of how loud she is later.

Here's the video of what she sounds like now.

Just got back from a day trip to Prineville Reservoir, and the XJ towed this beast back and forth between there. People at the docks were amazed that she towed the boat so easily. God I love my Jeep!
