Review on Alpha Rider Exhaust Manifold Sportster by Garrett Craven

This spacer is only 1.7mm thick. The thickness of the original is 2.5 mm. This may seem like a small detail, but it is actually very important. correct conical pipe connection (at 951/947 for 1998 seadoo gsx lt). If you change the thickness of the gasket, you will not be able to use the original installation of the pipe brackets that attach the two pipes to the engine block. I didn't notice the gasket was thinner until I spent a whole day cleaning it and trying to reseal and reinstall it. An absolute nightmare. You must specify the thickness of the pad. You can see this seal compared to the old one in my picture on the left.
