Hey, Welcome! Nice looking truck you have there! Good job on the wheels. As far as the exhaust, the advice usually given is to wait until you go on a run with the club and then you can check out in person what others have done. Since you will be offroading, you may find that other mods will take priority (sliders, skids, recovery, lift, etc.). Check out the sticky "Xcursion Guidelines" in the Xcursions forum to get some ideas. But like Paul said, it's just too freakin hot right now to hit a lot of the trails.
