i was going to go with bbk lt's, bbk x-pipe (for the lt's) and flomaster cat back for my exhasut soon. what else do i need to get? what kind of gaskets? do i need new bolts or does it come iwth em, and doe i need o2 sensor extenders? some ppl also say that you can "cook" your alternator with the lt's, is it wise to just wrap the lt's in header wrap?
