All that will change with the BW muffler when headers are installed.
Your correct as long as your happy with it. My point is 99% of the people who keep the Titan will expierence a cracked manifold at some point and the muffler and canned tuner you purchased will not work with headers at that time. You could have saved some money and went with what does work when that time happens. That was my whole point trying to save you some $$$ down the road. Im all about that doesnt matter if you buy from me or Joe Blow. Keep us posted on your install.its not a "wrong" choice if im happy with what i got
if i want to upgrade later on, like i mentioned, ive seen the 274 threads on uprev
