Here is a member from south Cali selling his 2012 & states he’s running aftermarket mid pipe but has all his stock parts. Maybe he would be willing to sell you his stock pipe with cats if you decide to go that route.
I just got a 2012 GT500. Took it to AED got a tune, Shaun told me that one of the catalytic converters is going bad(due to previous owner having incorrectly gapped plugs). Wondering if any of you can point me in the direction that can either gut my cats or, if really necessary I'll replace the midpipe/cats stock and just need a shop that can do that.
