What would you do?

I patched the downpipe last year, but it still has an exhaust leak at one of the ports on the driver's side. If I'm going to dig in and fix that, I might as well replace all the old piping. For new exhaust I'm considering...

A. Keeping it stock with single exhaust.
B. Stock manifolds with duals.
C. Headers with duals.

If it was your car, what would you do?

its all about intended use.. if it was my car and i didn't care about 1/8th mile times because its just a cruiser i'd keep the manifolds and throw dual exhaust on it..
