I got a hold of what I believe are 2 VQ30 y-pipe circular gaskets (P/N 20691-38U00). They look like they are the same size with the gaskets used on the 3rd gens, but I don't have one on me to compare. So just to be safe, anyone might know if these gaskets would fit on our y-pipes?

If not, then I might post them up for sale. If they fit, I might use them when I need to replace the rear exhaust manifold.

 

How is anyone supposed to know this? Go to the dealership and ask for the VG gasket and compare. Worst case scenario you find out for yourself while working on the car and have to go to the dealership for a $5 gasket.

 

according to felpro there the same part..
