OK, I did a search on "pipe install" and came up with WAY too many threads to go through for a few simple questions, so I'm asking them here. I took my pipes (BigShots) off to work on the rear end. I need to re-install them now. Do I need to do anything special or can I just put them on and tighten? Are there specs to tighten to, or is there a certain feel to it? Do I need to use any kind of sealer? There is a reddish looking sealer (or something) on there now. Any help would be appreciated.
