hedman headers with stock dual cat?
I am dropping in a new motor, and I want to know if hedman headers can be used withe the stock dual cat y on my 90 IROC? I am on a budget right now, so I can't jsut but a new y. I am very good at mig welding and have a welder if I need to cut and weld, but I need to know if it can be done and how.

Not directly. You'll need to re-route, re-flange, etc.
Hedman makes a decent set of dual cat headers, 68491, that will bolt in (after cutting the stock pipes off the cats). Bound to work better than what you can cut & weld up without getting a bunch of mandrel bends.
