the LTs vs the mids yeild in a little bit more low-end TQ, but it depends on the compilation of parts. are you going to run cats/emmissions? most people who go LTs delete both, which will save some weight/room and have a little less restriction. BUT, the LTs also have ground clearance issues on lowered vehicles. i have mids and they fit great( all tucked in there nice and neatly) while still having an advantage over shorties. it all depends on what route you're going to take. just make sure that whichever you get is coated. you'll be much happier in the long-run.
cliffnotes:
LTs=more low-end TQ gain but ground clearance issues.
Mids=slightly less low-end TQ gain but no clearance issues

unless your car is lowered you shouldn't have any problems i just put my longtubes on (not that bad really) and they didn't really cost me that much ground clearance, not enough to even worry about.

Just to get my facts straight, Mids are NOT shorties, right? So I guess my Q then is what is the difference between all three (if mids aren't shorties).
The reason I don't want LTs is just due to I don't really want to dick with them lol I'm not one to "go big or go home", for me, me car rocks, but an easy install of something I'll gladly go for like shorties or mids.

More torque in the low- to mid-rpm range is important to rodders who want that feeling of seat-of-your-pants performance on the street. Longer primaries also reduce the chance of escaping exhaust's being drawn back up another pipe.

Primary-pipe diameter establishes the peak torque point, so changing the pipe length will rock the output curve by pivoting it around that peak torque point. Graph B shows how longer tubes tend to increase power below peak torque while hurting power above peak torque. Shorter tubes tend to affect the engine in exactly the opposite way, hurting midrange torque in favor of increasing top-end power.

My car has mids, I desk top dynoed my car with Lt's vs mids, I made more torque with mids with less overall horsepower. LT's added 10 additional peak horsepower but 2 ftlbs less torque. Hope this helps. Formula350 mid tubes went on easily no loosening mounts, or removing anything crazy, not even the starter on pass side.

all headers are a pita on these cars or any v8 for that matter. you still go through the same work between shorties and lt's just the shorties will be slightly easier to get lined up. imo for the day of work you have to go through the extra 30 min getting the lt's lined up will defently be worth. the only real advantage shorty vs lt is that the shorty will hook up to stock y-pipe, and they should defently pass emmissions no problem, depending on which brand of course.
