The dual comes with some power steering relocation lines. It can be messy even if done with great care. The plastic pieces that the stock air boxes attach to at the front have to come out and they won't come easy if you cant find the pushpins holding them in. I never did find one of them. I just yanked real hard in the end. The performance improvement is real. The first time you floor it, be sure you have no other cars around and lots of room to gather it up if necessary. The first time at the drag strip with the dual I was looking at the concrete wall in first, let off, got it straight, hit second and was looking at the concrete wall again. And the supercharger sounds like a banshee at full song. Just poking around you don't really hear it much, or I got used to it.
