I put the JBA catback stainless exhaust system on my 2004 Titan. I did it for the V8 rumble more than anything else. Kept it until a few days ago when I got the Colorado. Still no rust on the exhaust. Can't say that about the rest of the truck though. Somehow I don't think you will get the same effect on the V6 unless you like that sound. Not for me though.
