I'm pretty sure FI means Forced Induction. Ie supercharger..that's my guess. LT would be Long Tube Headers

Yes, Adam is correct FI forced induction.. The true dual set up really is a desirable thing to me based off the Commanders sound it had, despite being a not so great job done by the idiot who did it. The cost isnt a big difference compared to not getting them done. LTs or long tubes, with new cats looking around 900-1000$ before install, plus whatever muffler(s) Id get. The Ypipe that comes with the LTs does not have cats in it, but Im getting a pair of high flow cats from a forum member to be welded in. I may keep the Y pipe going into a single inlet, dual outlet Delta 40 Flowmaster. If I dont go with cats Ill definitely keep the y pipe and single inlet to maintain some back pressure and avoid any rasp... Really want cats installed though to keep the low end tq numbers up from what Ill lose with LTs, which makes me want to install 6.4 srt8 manifolds, shorties, and custom mids to keep low end up as thats really more important than the extra 10-15hp up top.
