well from what i know the first cat is for cold start emissions, wich i dont have to do. i do need to do regular stick the thingy in the tailpipe emmsions, but yea. i was thinking of taking off the first one eventually. and replacing it with a straight pipe. then maby put in a hi flow for the second one. i have been hearing a little rattle and possible leak by the cats though. but its hard to tell because there is a little exhaust leak at the top of the new muffler.
well whenever i get my damn garage back ill be working on it more.
