Mazdaspeed Forums - UR V2.0 Downpipe

Upon receiving the standard metal core catted downpipe and mocking it up to an ATP turbine housing noticed that the flapper would contact the DP flange after opening. To a certain degree, that is also the case on the K04 housing but since the flapper is smaller it has more travel. Many running this DP with the K04 so I suppose it's not a problem.
Contacted Ultimate Racing to point out the issue thinking they would probably just brush me off and not address the problem. To my pleasant surprise they immediately asked that I ship the DP back to them with both the K04 and and the ATP turbine housings so they could take a look. A week or two later they had fixed the issue by increasing the size of the bellmouth and revising the flange. Those shmexy canucs are solid people. They sent the DP back to me and it works like a charm. No contact of the flapper against the flange anymore. Dealt with a dood named Daryl. He says UR will call the revised DP the "version 2" and that it will retail for slightly more than the standard DP. Welds look high quality just like the overall construction of the unit.

Tried removing material from the flange to increase flapper range. Results unsatisfactory
