I have a brand new c900 heat shield for over the cat on a c900 and from what I have heard, these are now NLA. I have 2 c900's: one that sees summer duty and a winter beater that is rusting to the point that this might be it's last winter. It also needs a new exhaust. I'm finally getting around to finishing it (seeing as the snow could start any day/week now and I want to get the good one off the road)...
So, of course the old heat shield is virtually unidentifiable and I've torn it off. I have the entire interior out of the car, but the front screw is not viable to use short of drilling into the existing "fastener": there is so much rust that the "fastener" is no longer recognizeable - not a screw, maybe a welded nut, but so corroded I couldn't tell and from the bottom it looks completely flat. I didn't want to risk making a bigger hole there attempting to remove it and fiberglassed over it (the interior floor is now a boat hull). All the other 4 fasteners are good.
I have a bosal after market cat which is wide and rattles against the heat shield (pulled from my other car - that's how I know, see photo below). It has a crappy little integrated heat shield. I would rather not melt my wires or cause a fire. Presumably the long heat shield was to protect against heat radiating from the pipe as well as the cat - there must have been reason for them to do that, no?
So, would you:
A) install the good heat shield recognizing that it will not fasten properly up front, will corrode in all the salt and slush of winter, and rattle against the cat. It would probably still be reusable after 1 winter but no longer "new".
B) hack together a DIY heat shield with sheet metal and the spacers for the back 4 holes, to cover the pipe and maybe part of the cat, recognizing that there is no good way to support/affix anything past the 4 rear holes.
C) throw caution to the wind, just ignore the heat shield, it's frikken cold in winter anyway, right? at least it will be easy to install the cat without rattles!
I'm not sure the best strategy. your opinion? thanks!
