Same setup I have. There is a noticeable clunk every now and then when the suspension unloads and ratchets up into the springs. Especially if you hit a bump that unloads the suspension, the reloads it, then CLUNK. But not too obnoxious. Side exhaust is almost impossible. I want to do a side exhaust, and haven't figured out how to do it yet, so if you figure it out, let me know. The takeoff is GREAT!!! instead of the rear sinking like it used to, you feel the rear just seating itself, the the front rising. Makes you feel like you are popping a wheelie, even though you aren't (or maybe you are???). I really like the cal-tracs. First time I gunned it, I felt like my head was going to hit the headliner, because of the front lift. Cool...
