Review on Genuine Nissan 20691 57E01 Exhaust Gasket by Mike Cox

Gaskets are a multi-purpose item, can definitely be used for different applications, but in my case; I used this on my 89 240sx with ka24e. Comes in a small packaging. This is a gasket to connect the front pipe or downpipe to the exhaust manifold (manifold). Since the exhaust goes from 4-pipe to 2-pipe connections, I needed two of them. It took me a long time (4-5 hours) mainly because the nut was in a strange place. Regardless, I took it out only to find that the old gasket was burned and very brittle. I have included two photos to show you what you will be receiving and replacing
