I just purchased a used 20 hp Briggs, the exhaust is pretty rusted so I wanted to replace, looking for an option that will perform better then stock. Anyone have any opinions? Buy a Stock exhaust and gut it? Or does someone make a aftermarket exhaust for the 20hourse? How about a set of these: http://www.bmikarts.com/Header-Pipe-for ... p_901.html

Next the carb either needs to be rebuilt or replaced, so thinking of going aftermarket performance and upgrading right away, best options for the 20 horse?

Since the exhaust and carb need work anyways thinking of upgrading those first but if you have any other performance suggestions let me know. Not looking to spend a ton but also want it to still be reliable. Also finding performance parts are a little harder to come by for this motor vs the 23briggs.
