2ZR LONG TUBE HEADER POTENTIAL GROUP BUY! - Toyota Yaris Forums

The soot ring is probably due to the gasket being about 1/4-1/2" bigger than the port, the 1nz has the same issue. You can gain quite a bit of flow adding a venturi in the collector. I've got a dwg of the flange if you want it, since I've already made a few headers.
