yeah what i meant about the cats was if you just cut them off and welded some pipe in place of the catsI think it did throw a code but I don't really remember. Just delete the rear O2's. Thanks.
It's the Borla XR-1 Sportmaster.
Idk what ur asking bout the cats but I cut them, used a pry bar and hammer to knock out the honeycomb, then welded them back up. Thanks.
