If your exhaust system has the long pipe off the big muffler pressed together with a clamp like mine did, throw in the towel and take it to a muffler shop that will do aftermarket work. It's not worth it. I did mine myself, and I had to carefully cut a slit in the end of that pipe where it is pressed together to take the whole exhaust off without shortening the Y-pipe. A muffler shop would've taken about a half hour to install it, instead I spend about 4 hours fighting with that damn thing. Minor rust doesn't help the process. My K&N took about 35 minutes with about half the tools I needed (didn't feel like walking upstairs to get the tool box). If your stock box comes off easy, you won't have too much trouble.
