"The info stated an exact fix, no welding....NOT!
The catalytic converter does not come with it. They do not sell just the catalytic converter for the 2004 Titan. So do you cut the old one off and hope is was not damaged from the reason you are changing it in the first place?
Poor design by Nissan." —Wayne W from Fredericksburg, VA bought a JBA Cat4ward Headers for a 2004 Nissan Titan, 5.6L V8.

"Everything is very good. The only thing that wish JBA would have done is run the header through a degreaser before shipping to remove excess metal shavings inside the pipe. Other than that I am very happy. I would recommend" —Ronald M from Lovingston, VA bought a JBA Cat4ward Headers for a 2004 Nissan Titan, 5.6L V8.
