I've sold a bunch of mariner and kerker pipes for the 300 motor on ebay, but according to one of the few guys I listen to on jetski stuff,says aftermarket pipes add an insignificant amount of power, if any, on the 300. I know they come high performance from the factory with higher compression, like 175 and the design of the stock pipe gives good performance. cylinder porting is going to be the best perf mod. maybe a 38mm carb instead of the 34mm and a good stainless prop. I have 6 or 7 js and sx 300s also if you need parts. i'm not going to sell you something you don't need. maybe try and dry out the stock pipe so it doesn't dump as much water in the chamber. don't dry it out too much or you'll burn up rubber couplers.

Thank you for the advice Buzzard. I am searching for the pipe for a friend. Do you have a Kerker exhaust you are willing to sell? Perhaps drying out the stock exhaust may yield the same gain...
