Inspect the engine mounts while your in there dollars to doughnuts one or both are broken. The 90-92 exhausts had a restricted resonator. If your keeping the stock exhaust swap that out for a later one, x pipe or Dynomax Ultraflow Welded X resonator. Exhaust system fabrication to some degree is unavoidable when your doing headers.
Have fun.

Everything is tight in there...…..
What other emissions hardware gets removed? AIR plumbing? Can I keep that stuff?
I've been looking for a stock replacement 93-95 resonator, but they seem to be non-obtainable. Hopefully something like the Dynomax will keep the "drone" out.
