If they're stretching the collector primaries that much it should have been dubbed over to a T4 flange, instead of jacking a smaller T3 flange and porting the crap out of it to the point where it'll cause major flow issues at the juntion of that flange into the volutes of the turbine housing.

again as you stated off hand ebay headers

interested in your suggestions I like seeing thoughts explained. I recently developed a collector for the 993 heat exchangers and it was so confined that it makes it hard to get 2"X2 into a t3 flange but It worked out well
