The Former Owner was the Dealer Owner and he said he been to Germany bought stuff, I'm not sure if he got the Extractors, Chip and Cams then.
I think Genie and HM Headers are working on Extractors for Both SRi Models. HM Headers make all the Exhaust for HSV and Tickford so they should have come up with some thing.
