I got my HKS downpipe a few weeks ago, and I just got my catback on Saturday. I am going to do my installation of the whole exhaust this weekend. I want to make sure that I have everything I will need. I have all of the tools, but I am worried about breaking some bolts and/or studs...does anyone have the sizes of the bolts/studs/nuts that I may break. I want to make sure I have everything on hand before I start this project.

Any help will be appreciated. Thanks.
