I think @Rdrttoy uses/sells these and might know?

I believe they were supposed to give you a few extra RPM, not a mod you'll likely feel but a little bump when you're trying to get the most from your setup.

Yes, we have them. Good to use in a lites class ski. It is a small gain, but a gain none the less. Best with other mods, dried out exhaust, etc.

How can you dry the stock exhaust out more.

Re- route, and Restrict incoming water.

High speed industries sells them in a kit with high comp head gasket, instruction on water routing, and new jetting for $115-150 depending on your setup ( single or dual carb/ opt in or out for head gasket) more than a fair price for a little gain considering the guys done the homework for you.

You'll have to imagine you're feeling it. A loud waterbox makes it easier.
