Has anyone installed a set of JBA headers for the Titan. I wanted to know of the power gains after installing the headers. I heard that they screw up the o2 sensor on the cats. Is this true?

Dont have them but I have been hoping a set would mirraculously appear at the house one day. If I ever hit the big time I'll try them.

I don't have the headers, but since they have to be CARB approved as 50-state smog legal, I can't see that they would hurt the O2 sensor(s). A word of advice: wait awhile until some of the other manufacturers start building headers for the Titan. I looked several weeks ago online at the JBA's; be prepared to shell out about $900 for a set of their ceramic-coated headers. Once Hooker, Heddman and some of the other brands start producing them, the prices should come way down.

Just bought the JBA Titanium Coated headers for my 05 Nissan Titan 4x4 Off Road and can't wait to install them. I got them for $630. I also installed a K&N Air Intake System and a GIBSON exhaust system. Will let you know how it works out

JetTech installed JBA headers.

Good luck! No, seriously....you're gonna need it. Take some pics for us, too!

The gains aren't supposed to be THAT impressive either. Long tube headers are starting to be produced from other companies, and that's what I'm holding out for...
