Im new here just picked up a 2008 g37s and purchased a used tanabe axle back and tanabe mid pipe. I am trying to figure out what gaskets I will need when I install these parts. They all seem to look the same in pictures but I noticed they have different part numbers? Can anyone point me in the right direction it would be appreciated

 

Whatever fits the ID. Some use no gaskets. Just RTV copper high temp sealant.

or

2007+ Infiniti G35/G37 Berk High Temp 2 Bolt Cat Pipe Gaskets(Pair)

I would recommend ordering from that site as they are a sponsor on here.

 

Thanks guys. So these gaskets are the same then for all the connections? The mufflers to mid pipe, mid pipe to y, then y to cats all use the same one right?

 

the gasket between the y pipe and the midpipe is larger than the 2 between the cats and the y pipe. I just got these 3 gaskets for $10 from rockauto.

 

Sigh I am very confused now. They all look the same in pictures and none of the sites I have found or been sent seem to clarify what they are for. I cant seem to find any on rock auto for the g37.

I did find this site but not entirely sure which ones I need as they look exactly the same in the pictures. Which one do I need for the mid pipe to Y pipe?
