How do you replace the front flex exhaust pipe on 2000 Honda Passport

Hi! I need to change out the front flex pipe, it has a leak, and I now sound like I drive a Harley! YEAH! :)
Looks like an easy enough change out. Is there any welding involved? I took it to the shop, they made it seem like it was a pretty easy change out, he was willing to do it at end of seems like something I can do, as save a few bucks. The part is cheap, itself. what ataches it to the pipe? thanks!!!
