Undertail exhaust!

I have been looking for an exhaust for a while now and nothing I like. I went with a strait pipe, looks great, but it's just too loud. So I'm looking into going with under-tail and since nobody is making a kit I decided to make my own but I still need slip ons. I'm looking for the smallest slip ons, Arrow and Chain-reaction are the only two I could find so far but the price is way up there. Any other slip on you guys think I should look into?
