89 STD question
on my car the stock manifold had a cat on the manifold, i replaced the manifold with a header and a catco. cat. my headers arent CARB stamped and i was wondering if it would hurt anything to put my stock manifold on for the smog test and run the 2 cats.

2 cats gave me a really really quiet sound when I ran it back when I had my 70HP engine. I liked it. Don't know about emissions, but free bumpage to you.
