Just grabbed a brand new JDM ITR catback exhaust. Which gasket should I use between the b-pipe and muffler section? I don't think the USDM exhaust gasket is the right size.

 

Alright so I picked up a factory b-pipe to muffler gasket at the dealer...it reads "60mm to 54mm" on the bag. I don't think it's going to work.

Would an exhaust shop or auto parts store stock the appropriate gaskets? I'm not sure if that goofy ring design is specific to Hondas, or is a pretty generic gasket style.

Thanks in advance.

 

The stock USDM gasket should work fine.

 

Thanks, I guess I'll have to wait and see. I figure I might be able to use my Dremel and grind down whatever doesn't fit.
