the car runs fine and has cold air conditioning. it does have two issues...a cv joint clicks...and the alternator needs to be replaced. as far as ceramic coating the exhaust manifold, exhaust housing, o2 housing...that is probably going to happen along with a slight turbo upgrade. otherwise, i'm just going with a downpipe, exhaust, eliminate the cat and go with a slightly more free-flowing exhaust. as emodsm has already mentioned...i usually get a little carried away with each vehicle i have and more mod's end up happening as a result...however i'm gonna try to keep this car as stock as i can.
