It has flow masters on it now, but the exhaust is so scabbed together that I'm going to replace everything and start over. Looks like it has the factory Y pipe to at least 3" pipe dumping in front of the rear dif, it's terrible. I didn't know that Flowmaster makes the correct Y pipe that'll bolt onto cast iron manifolds, trying to stay away from the exhaust shop.Called the only local machine shop we have for prices to get the stock manifolds cleaned up: bake $60 pair, plane if needed $120 pair, I'll get the studs out at home otherwise $60/hour for that.
