I am going to swap my ART pipes for FI RHFC and looking for info on the 3 hole gasket between the cat and the manifold. Since the ART pipe uses the oem ring style gasket and the FI cats don't, I will need new 3 hole gaskets. I might put the ART pipes back on, so I don't want to use RTV.
Z1 has metal gasket for this purpose for $50 shipped.
I also found 2.5" gasket from Vibrant that appear to be an decent option for under $20.
Common sense says the Z1 gasket is the better choice, but will the Vibrant gasket get the job done? Anyone has experience with the Vibrant gasket. I assume this is a universal bolt pattern.
