Re: Catalytic converter woes
I wouldn't remove the muffler if you're gonna do a test pipe. It will be so raspy and loud, you'll hate life.
When mine went bad, I actually used a HushPowerII (I think?) resonator/muffler with some flanges welded on to replace mine. It passed the visual inspection for a converter in my area and with a defouler never threw a CEL. I realize you don't have that but just an FYI.
