Default specs on cats



Tired of searching in all the wrong places. Need to replace my 2001 stock cats. What am i looking at for pipe diameter, in and out. I think it’s 2.5”
With Magnaflow (quality?) or similar hi flows, are there any major issues with throwing codes, short of major retuning?

Thanks!! GRT

Do yourself a favor and buy the complete OEM replacement 2002-2004mid-pipe with cats assembly. It will bolt up to 2001 exhaust manifolds and tail pipes without any modifications. In 2002 the pup-cats were eliminated resulting in reduced exhaust system back pressure. The complete mid-pipe assembly with cats can be bought for under 600.00 new and around 150.00 used.
