Hi Craig, welcome to the forum i signed up not long ago all seem to be a friendly and knowledgable following i was having a look around on ebay earlier, if you type in punto gt breaking theres a silver gt3 in middlesex london and theres a yellow one on pistonheads cant remember if its a GT3 they might be able to help you out, im not sure if theres any aftermarket manifolds for the punto but a member with a tuned car might have done the research on manifolds and turbos already.
