What is the different between long and short tube headers. I've been looking around at both wanting to buy, but i don't really know the difference.

 

you wont really gain anything with shorties but you should gain a little with longtubes. the longtubes should flow better. the only problem with lts is that MAC is the only company that makes em for the 3.8. it sucks because i dont like mac but its your only choice. you will also need a new midpipe or a custom bent midpipe from a shop for lts though. the shorties will bolt right in.
