Have seen these ages ago - go to the 3rd picture down - http://www.volvoforums.org.uk/showthread.php?t=17006 I think S60 maybe 740 Volvo and Miata's run them The entry of the wastegate gases seems better than 300zx gases and the exhaust pipe connection is a whole lot tidier easier Cant find any exhaust housings in our size - Miata is .45 which would spool lol I'm open to abuse - good idea - crap idea - been there done that - anyone know of T25 or T28's Garretts with this design exhaust housing in .60
TBH, probably only a change for changes sake. No reason not to run them. They will work fine.... Wastegate gas does not come out nice and straight or evenly like a poppet style valve. The gas exit angle is close to irrelevant when it just expands into a dump pipe. E
