Review on Walker Exhaust 31377 Flange Gasket for Exhaust Pipes by Sean Maile

I have a problem with my downpipe and the cat fixed this gasket. Neither tube has a bracket to install the seal. This means that when you tighten the bolts to connect the flanges, you're basically guessing if it's in the right place. This expander gasket has expanded sufficiently to seal the surfaces where the tubes meet. I think it's a simple sheet metal pad. It took a decent amount of effort to start compressing and get a good seal. I'm sure it will last longer than the pipes, their sealing.
