cheers for the replies folks.
spoke to a mate who has a couple spare from his 300zx turbo/dump upgrade.
assuming these fit it should be installed by tommorow afternoon

well the system is installed on the MY03, looks and souds awesome (loud!!)
performance is interesting (no tune yet), seems a little laggy in throttle response but hauls serious ass when its over that hurdle

2 issues ive found with the BPM GT system:
- the exhaust length is actually too short, the muffler tip is under rear bumper by about 1cm (hangers and everything fit perfectly without modification so i think this is intended)

- on hard left turns the steering column (i think) is rubbing against the wastegate section of the dump. not sure how i will get around this one (might have to create a groove on the dump to allow room)
