Where can I buy a bolt up replacement cat or, bolt up replacement pipe for my 86 sr5? The one on it now looks like the original from 86. 220k mile later, it must be bad.


If you want to go through the trouble of replacing it, you should at least inspect it first before you buy a new one. Japanese cats are constructed like a hollow brick of fine square passages. I replaced mine (had to...it failed smog testing at around 125k). The muffler shop fella showed me the cat and the brick was 80% missing! I guess it fell apart and blew into the muffler. I got a hi-flow unit and went 2-1/4" aluminized tubing with a muffler and haven't had any cat/smog issues since.
