Yes, you can rince it out with any oil and it will have a slight beneficial effect. No idea if the 350F aftermarket 4 into 4's are any good but unless you're riding it every day doing 12,000 miles a year, I wouldn't worry about it to much. The worse thing you can do is keep starting the bike up, creating condensation and then not running the bike for long enough to dry the condensation out. That's the main killer for the exhausts.
