Background: 91 ZR-1, headers, no cats, straight pipes from headers back to mufflers - no resonator.
As I was gutting the interior from my 91, I found that the passenger side corner, where the floorpan meets the trans tunnel as it widens for the bellhousing, was burned by the exhaust, in approximately a 1" diameter circle. It was not burned entirely through, but all that remained was fiber strands, no hard substance at all. The carpet padding overlying it was completely disintegrated. I never smelled anything burning, so this may have happened when the previous owner had the exhaust done, I have no way of knowing.
So, what to do? Obviously I need to patch the hole, but more importantly, I suppose I need to fabricate a heat shield? Or do I just have a muffler shop bend the pipe a little?
What should I use to patch the floor pan?
Thanks!
Andrew
