Nissan 370Z Forum - View Single Post - Which of these gaskets should i use? Installing XYZ Y-pipe

Im installing my XYZ y-pipe and im wondering which gasket i should use to connect to the cats.The one from the shop that put on my HFCs? or the one that motordyne sent me. Or both?

This first gasket(s) was installed with my HFCs about 2 weeks ago. The silver one is towards the rear. The multi-layered copper gasket is getting burned.

This is what motordyne sent me for the cat and midpipe connections. Are these supposed to be used in addition to other gaskets?

Lastly here is the old gasket from my stock Ypipe/midpipe connection. Looks toast

Thanks for any help as im halfway through my install.
