It is probably in-house custom bumper as
shv2sail said. I have seen their
rear-tube bumer in person back in '02 or '03 at Calmini site (Looked pretty nice). Calmini being a custom off-roading equipment manufacturing company, I'd incline to believe that they made that front tube light bar for pathfinder.
The owners (brothers) of the company basically have 2 lines of business:
Calmini and
Full-Traction. They operate their businesses in one large warehouse. One side of this warehouse is for Full-Traction, and the other side of that is for Calmini. They do understand from years of doing business that while there are some demands for Susuki/Nissan vehicles, there are much larger demands for domestic vehicles. Since they're in the business of making money...just like any other businesses, when it comes to deciding where to put more time and money to produce products, it is unfortunately clear what market that is.
You can send them an email, but their replies typically wouldn't give you the kind of specific answers you are looking for. It's just much better to make a call to them if you wanted to find out more (whether it's a good news or not so)...speaking from my personal exeprience.
