Happy 4th of July! I have been inactive for a while but glad to be back. My 88 GT Vert has BBK shortys, O/R pipe, and when I put on the GT40P heads I had the smog pump and related emissions removed. Now I'm getting a thin coating of exhaust on the paint. On a white car it looks bad, plus it is VERY stinky. Three questions: Is it normal with this combo to get a coating of exhaust on the paint or is it running to rich maybe? If I add just two high flow cats and nothing else will it smell a lot better? With no other emissions stuff will those cats get plugged up easily? Thanks.
