I just got through having my spare manifolds removed from the 94 bonny. The back manifold had no cracks at all. The front had a couple of cracks in the middle tube and plus a blow out up where the 2 manifolds attach to each other. I think this car at one time had a very major exhaust restriction. So now I'm gonna get the manifolds welded for free and have them ported and on alot sooner than expected. One other question. If I send my Jet Chip back to them will they modify the settings?

I'd be surprised if your rear manifold was really crack-free. Some of the cracks are TINY, or hidden by welds. I can't answer your JET question. I've never bothered (point to be made here.....my car runs great on their stage 2 burn still).

Yeah my car has never ran much different over stock even after the Jet Chip. Hopefully I can see some new gains after fixing my exhaust and getting a new fuel pump.
