If you have a 05-09 there are no gaskets. It is a ball and socket joint where the mid pipe meets the manifold. As far as clamps go you should be able to reuse them but make sure you get 2 with the off road pipe. If not you have to pick 2 up at a autoparts store. Make sure you got the right tools before getting into it but like he said above, don't pay someone to do it. You have to eventually put your stock H back on to pass inspection and emissions anyways so might as well just DIY. A torque wrench and breaker bar along with a 15mm deep socket and some PB blaster and you should be good to go. Hardest part is getting the stock H off and the o2 senors out...
