Catalytic Converter: 01 SS SLP Exhaust upgrade OEM CAT?

**kodiak120** · 08-08-2014, 05:16 PM

All,
I tried replacing my passengers side CAT with an OEM replacement direct fit from Autozone:
Walker New York/Catalytic Converter
For your 2001 Chevrolet Camaro 5.7L SFI 8cyl
Warranty: 5 YR

The shop mechanic said it was a smaller diameter and is not the equivalent replacement. Is this a common problem or is the SLP exhaust upgrade at factory purchase also an upgrade to the catalytic converter. Any suggestions for what brand to replace with?

I would think that the SLP upgrade runs the stock manifolds and converters for emissions... but honestly am not certain.

Was it P/N 53437?

53437 Yes, that is the part number of the walker replacement I attempted to get.

Any suggestions for replacements which have shown compatibility and direct fit? My preference is to keep things equivalent between the passenger and driver side.

They show another P/N on the website that is shorter.

I will have to check, but I have a used stock slp cat that I took off my buddies ss camaro back in may. Only had like 30k on it. I put after market exhaust on his car and deleted the cats. Nothing wrong with them at all, I just gotta find out where I put them.
