Hello, I'm purchasing a used catback with an invidia test pipe included. I need to buy my own gaskets separately. It looks like I need the house shaped 3 bolt gasket to mate the test pipe to the catback, and two more oval shaped two bolt gaskets for the catback itself. My question is I can't figure out if I need a gasket for the other end of the test pipe or what I would need. Any owners that could confirm what's needed would be appreciated.

 

The test pipe side that connects to manifold should already have a gasket. You could replace it since you are already down there. I changed mine just bought another one from autozone. I have had no issues with it.

 

What kind of gasket is it though?

 

You mean where it connects to the header? Just reuse your stock donut gasket.

 

Yeah I would. Just do a visual make sure it's not damaged and seats properly. If that's the one you are talking about. If it's the triable gasket you can go to any car parts store and they carry them. I don't know a part number and I'm sure they won't either but they will have it. Look on their website first for a number.
