I've wanted to make a divorced downpipe ever since I saw Corky's new downpipe design. This past week I finally had some miata time and put one together. The main reason for upgrading my downpipe is because I was experiencing boost spiking at 12psi with my gt25r. I tried adjusting it through my EBC, but never could solve the problem. So, I thought it might be my downpipe design. I've since installed my gt28rs and have been running my old downpipe with no boost spiking...but I'll save that for another thread![](https://www.miataturbo.net/images/smilies/smile.gif)
During installation, I ran into a snag. I was unable to get a good seal at the downpipe flange. I had the flange sanded down, but still was getting exhaust leakage. I broke down and bought a gasket off of ebay the other day. I did not want to disassemble the flange and have it milled flat. Hopefully I'll be able to test this thing out Saturday.
