360 Tubi Styles Install.

Have a 2003 Ferrari 360 Modena USA model and removed the original exhaust headers (what a pain) - I purchased Tubi Style USA model headers with air rails, wondering if anyone has installed these, and if so hopefully access to put the nuts on is easier than removal from the original headers? Also purchased the Fabspeed sport cats to marry up with the Tubi - the Tubi does not have the upstream O2 sensor bung so will reconnect it to the input of the Fabspeed cat on both sides - anyone who has been there/done that comments would be very welcomed. Regarding headers nuts reinstall access (particularly the front on both sides) am thinking access may be easier by removal of the firewall access panel, the one used for timing belts access...

 

Interesting, yes see the small crack line - will check mine also - hopefully anyone who has installed Tubi Style headers may have some suggestions/comments on how easy/hard the install truly is, particularly with very limited access....
