Is there a recommended site for purchasing a Gibson exhaust for my Titan and, considering the size, would it be a good idea to purchase this online?

I found the best price at www.streetdemand.com

Unable to connect to site. Unable to ping. Either they are having some technical difficulties or they are gone.

Try the links section of this site. Check this place out http://www.hopupracing.com/nissantitan.html

Thanks for the help. I found a decent price at a website linked from Gibson's site. I've got it on order...that's a new thread now. :D

I ordered mine from there and had no problems. However, there website did act up sometimes. I just called them directly. They were the best price I found.
