So, I recently found an invoice confirming my car was under full warranty up to 108k (It's now at 134k). The invoice has a couple gaskets listed, and I can't seem to interpret the numbers into which gasket one might be so maybe you guys can help me out.

10328740 Gasket

I'm thinking it's related to the Catalytic Converter.

Also on a random note, I did an oil and filter change through advanced (bought castrol synthetic) and the guy couldn't find the oil filter I needed with the sale so he marked down a k&n filter for me woot. I think I'm sticking with synthetic from now on, I've tried regular oil and the car just doesn't seem as responsive as it should.

Thanks

 

That's the gasket that goes between the Cat flange and the Resonator.

 

Thanks bud.. Wish I could find an invoice with a change on my lower intake or something awesome like that. Atleast I stumbled by the cat change though.
