Folks, as most of you know by now, myself and Karl have set up a company and we are the exclusive suppliers of RPW's parts in Ireland.
RPW have a V6 Header for the GR and GPX and are willing to do a group buy if anyone is interested, here is the link of the actual product. There was a very succesful group buy done in the UK and they've quoted increases in BHP by 15bhp.

go into product guide on the left hand side and it's under Header/Extractor Systems - 6cyl
I haven't got exact figures, it will depend on the numbers of interested people.
If anyone is interested let me know.
Cheers
Dave
