not that I know of. it's just one pop. it never did it before. I'm tightening everything I can get a wrench on presently. was able to get the bolts for my west coast fiero motor / trans mounts a bit tighter. I don't want to loose any daylight so I'm going to tighten stuff and take it for a drive(thash) again and see whats what. also I did notice that some gasket material was hanging out of the manifold flange where it bolts to the exhaust . maybe it's just one pop out of there that I hear. thanks.

think I got . took it out for drive. heavy acceleration / de and no popping. I am going to do something about some sort of gasket between those flange connections. the guy who did my exhaust used a flat flange on the exhaust side. I think maybe I need some graphite gasket material and cut to fit. thanks.
