I'm installing a stock style dual exhaust system on an original, stock '66 GT. After installing the H pipe to the original exhaust manifolds, it ends up not centered... a little closer to the driver's side floor pan than the passenger's...Before I try to modify it to be exactly centered, I was wondering if this may be how the original system installed, as opposed to being perfectly centered to the tunnel. It is, of course, almost impossible to find a picture of an original, factory installed system. I don't want to spend the time and effort to modify the H pipe to be centered if it wasn't originally any way. The car has not been modified in any way, and has the original exhaust manifolds, as I said.
