When I bought my 86 it had a full exhaust on it to include a cat roughly half way back the car and a coffee can muffler. I called around to local shops today to get qoutes to have it replaced with several different prices. I was told by one that the reason the other ones were so high was because on an 86 CRX Si the cat is in the exhaust manifold however they were adding an additional cat to the price. My ? is, was this guy telling the truth and it is in the manifold or do I need a seperate cat?
