More questions about headers....

I don't race,auto-cross or anything extreme. My question is, for my application,
is short tube or long tube better? What are the performance differences? If I DO
decide to do more mods, am I better off with short or long tubes? Thanks in advance for any info.:gears:

You can buy LTs with catted mids. They are about three hundred dollars more, but they are available. SLP, and Kooks have LTs with catted mids. I just put a set of Kooks LTs with catless mids, and it does make a difference. Lost a little on the bottom end, but man it pulls hard once it hits 4000 RPM. I need to get it tuned, and that should take care of the slight loss on the bottom end.:burnout:
