Yeah, it shouldn't be a problem. Anyone with experience could do all 3 of those installed in maybe an hour or two. If you're new to it, I'd say give it a Saturday.
And do not get it installed at the Dinan Reseller, you'll get ripped off horribly. An exhaust, chip, and intake are either installed or they're not... there's not much gray area.
And if you get serious about doing it yourself, I'll find you very detailed DIYs on how to do all 3.
Good luck with it.
