OEM cat to back box gasket

[bobbe]

Hello all,

I know OEM gaskets are recommended for the manifold to the cat. For connecting an OEM manifold to an OEM backbox, are OEM gaskets similarly recommended or will any of the various third party donut ones do the job?

Thanks!

Never had a problem with OEM doughnut exhaust seals.

It's not so much Toyota-branded exhaust gaskets, as the type....crush rings at the front.

The conical wire type are very common.  This should be fine.

I had a non OEM donut, it needed some fettling to fit over the pipe. I made it work but it was a pain.  OEM ones aren't that expensive, so I'd say go OEM.

OEM.. Do it right do it once.
