Asking because i'm looking for a new downpipe and would like it to fit. Does anyone know if a 3" H&S dp will fit?

 

The HKS Drager (not sure if it was a super drager, or if there's any difference anyway...) is/was a 3" the whole way through. The only non-standard part is the connection between the centre & backbox - the connection to the DP is standard 3" fit (not the wierdy Subaru 2.5"-with-o-ring sort of gastket, though). Just a flat fit. Same as H&S AFAIK .

 

H+S 2.5 inch or 3 inch downpipe will fit.
I have the 2.5. Sounds great - hear turbo spool up and car pulls so much better. Did not notice a big increase in noise overall.
