Nitex

you swapped the gaskets on the cats to the headers or the Y pipe? and did you swap them out for the factory metal gaskets or did you swap the factory ones for the ones supplied with the cats ?

I only ask because i just installed my stillen cat backs this weekend. I'm finding another shop to do my cats and gen3's. I'm not confident in the last shops ability. Anyways i re-used the factory metal gaskets from the cats to the Y, and im just making sure this is what everyone else is doing? The instructions called out to use the factory metal gasket.

Edit* Installing my cats and intake this week, ill make a thread post install with pics and videos, hopefully i don't get this code.
