Im thinking of changing my cat on my 99 with one from an 02. My question now is will the catalytic converter from an 02 TL fit and function properly on a 99 TL? I saw that they are different part #'s according to Acura (off by 1 letter or so) but aftermarkets are listing their cats as 99-03. Both vehicles are NON-California emissions. Thanks for your time everyone.

 

as long as the 02 one isn't a type-s one.
