QTPs are slip-fit collectors, 3".
I wouldn't go so far as to say they are junk though. They have a true merge collector in the Y-pipe, which is a feature I haven't seen in other Y-pipe kits. One could say it is difficult to get a good fit with the Y-pipe, but with a little creativity and alteration (in my case) I am very happy with it.
I know my car dyno'd 10+ more RWHP with standard collector QTPs and their Y-pipe over another car, set-up very similar, on the same dyno, with the same tuner. I think the Y-pipe may have contributed to the difference as the header designs we both very similar (he had Kooks I had standard-collector QTPs at the time).
What else do you want out of a full-3" Y-pipe with a merge collector?

You're only options are QTP or Custom. The QTP one looks pretty good flowing because of the collector, which is what I would do if I were to have it custom built anyway. Might as well have it custom built, it would prob come in cheaper and fit better.
