I use Marks (Performance Welding) merge collectors on my Pontiac. He really knows his stuff and they are great quality.
He is a great person to go to considering your combo. His small block A body that Steve Wann often drives is one of the fastest A bodies around. You should talk to him about what he does on his car. He actually has a second merge collector where both headers merge into one exhaust. Sounds a bit different but the thing sure is fast.
