I am in need of replacement gaskets for my Invidia N1 exhaust. The gaskets would be for the flanged connections between the Y pipe and mufflers. Does anyone know where I can get the gaskets? Invidia USA told me they don't have the gaskets. I tried O'Riellys and AutoZone, and they seem baffled.

 

I found the gaskets I needed.

Y pipe to mufflers: NAPA #31367, 2 inch ID x 3-3/16 inch BC
Resonator to Y pipe: NAPA #31307, 2-1/4 inch ID x 3-1/2 inch BC
