Tubi Race Headers

Guys, I wanted to resolve a personal mystery about the Tubi Racing headers for the 355. I have seen them installed on 355's for years but when I try to buy them. Tubi swears they don't make them. So, what is going on? They do sell them for the 360 and 355, but they are not street legal. Tubi does not advertise them. They call them "off road" headers. Go figure.
They are sold through a limited dealer network. It is a 4 into one collective without the heat shield. The 360 headers also fit the F355. I am not sure, if they make it with the rail or not for 96 or newer 355. You can order them through Ferrari dealers (if they know about it) and Ferrari racing shops.

 

It's a better set up for high performance. All four exhaust mandrels exit into one shorter exhaust tip. I will try and take some pictures of it.
