Stock replacement. The cats they make now have very little restriction.

I would go with flowmasters. I have long tube headers, true dual exhaust with no cats. I'm running magnaflows and they are very quiet

I have the Magnaflows, straight duals front to back no cat as my state does not test; they are really quiet, almost too quiet for a corvette.

They are brand new, I'm kind of wishing I had the Flowmaster 40's for a little meaner sound.

I put Flowmaster 40s on my 81 along with a free flowing cat (the old pellet style is very restrictive) and am very happy with the sound.
