First off, thanks to all the posters here because I've read through tons of postings deciding what kind of exhaust to get. I've also learned a lot in the past couple of days, but unfortunately, the progress on my IS will have to be slow as I'm in college. But at any rate, I was wondering what kind of tools I will need to install this Hiper, and if it's really straightforward. Any hints, etc. would be helpful as I get started on the long list of things I want to do. From everything I've read so far, it doesn't look too difficult. Thanks everybody.
