Catalytic Converter question

flipwhip41 · 10-07-2008, 10:56 PM

This is a stange and possibly foolish question, but do the stock h-pipes for 1990 gt's have 2 or 4 cats on them I seem to see 4 heat shields. 2 at the top and 2 at the bottom. can someone please clear this up for me?

I'm not sure on what they are actually called. One of mine, the front ones, was making noise and i took it to a muffler shop, he called it a cat. I ended up cutting one side open and removing the front ones. I live in Texas, they require emissions inspections, my car passes still. The deal inside was made out of a brittle gray material that was full of square holes, dunno if that's a cat or not, hope it helps.
