Well here's the update.
Some bad news, all Nismo exhaust are on back order until mid August.
Greg at Mossy is highly embarressed, he really could not apologise enough.
He has been in contact with Nissan, right up to Friday last week and was told everything was ok.
When I phoned Monday to sort the wire transfer, he told me about the delay.
He has been trying for the last couple of days to find them elswhere but to no avail.
I have also been trying lots of other companies.
They are all in the same boat, there just aren't any out there.
Some have 1 or 2 left in stock but not the numbers we want.
So we have 2 choices
1. Leave them on order with Mossy until they arrive. Still the best price I could find overall.
2. I return all monies and maybe try again in August, when there available.
Not much more I can say really, pretty pi**ed off though.
