This is the Grimmspeed 3-Bolt Up Pipe Gasket. This option is now available for those of you with vehicles equipped with the 3-Bolt Up Pipe option. With that said anytime you perform maintenance or upgrades that requires removal or replacing your up pipe, it is always a great idea to replace the gasket because, like all turbo or exhaust gaskets, they experience more heat than any other gasket on the engine. And just because the remaining gasket is made of metal, it doesn't excuse it from degradation. To prevent exhaust leaks and further labor, just get a new Grimmspeed Up Pipe Gasket.
This particular gasket is 22% thicker than the stock gasket and has a 304 stainless steel fire ring.
