I also had the ZZP downpipe which was much better quality than the CTI, but it also leaked at the 2-bolt flange. Nothing a remflex gasket couldnt fix though. Def. a quality downpipe for the price.
I now own a Random Technology downpipe. Best downpipe I've had on my car. Its a 3" to 2.75" downpipe (3" before the cat, and 2.75" after the cat), comes with a spun metal cat, and is leak free. It's pricey though.

You must have got a good one. My CTI downpipe was a piece of ****. It had a warped flex section (after a week of being installed), crappy welds, and an annoying exhaust leak. Not to mention the converter was welded in such a way that it rubbed and made an annoying noise everytime I shifted. I even hammered and bent the heat shield to help the issue, but nothing fixed it.
