[pre obd2 cats]

Just bought the magnaflow 3" spun cats part #59959, but just realized they are labeled as pre obd2, so will these work on my 03sss? Planning on putting them on with the coated pacesetter longtubes then a tune.

Question for the 59959 cats, the box says pre obd2, would they work fine on an 03 ss? Supposed to go on with pacesetter long tubes and a tune? Any personal experience help would be greatly appreciated, also want to note that I'm in phx az so I need to stay legal.

Wondering if anybody could help me, just ordered these cats 59959, but just noticed that they are pre obd2, will they work fine in an 03ss? Going on with pacesetter longtubes and a tune.

Hey just wondering, the bungs on the y pipe, those r for the rear o2s right, is there enough room to put the cats on between the y and the header?

Awesome thanks, so I just realised that the driver side cat would run parallel to the tranny crossmember, would that be a problem, looks like a tight fit, anyone have pics of this setup with cats? Also if I plug into the 02s that r gonna then run in front of the cat on the header will I run any codes? All these factors r making me lose faith.

Does anybody know if there will be any problems if I do this install to my 03 ss, then weld the stock cats on right after the header? I called a shop n they said it won't run right if I do that

Awesome thanks jc, do u still have your cats on, I still need mine on cuz I live in phoenix and this is my daily driver, if so do u think u can post up a pic of your setup

A question about the coated pacesetter lts, the pictures I see look like there is an egr flange on them, I have an 03 awd ss with no egr, does that bung come sealed or is there a version without it or what? Somebody school me on this please
