Just looking at getting this flange, I like the simplicity for making the downpipe which will be on the same side as my aircon, so it is going to need a very tight radius bend immediately. My only concern is the oval shape which of course is not identical to the T25/28 outlet (going on a GT2871R) will this restrict the flow because there will be small ‘lips’ in some of the corners around the wastegate? Personally I think that there would not be much flow in these areas anyway and it would not really be affected. Any opinions?
