If you're engine is stock and your gonna stick with that pipe, just put a set of carbon tech medium tension reeds in it. They aren't listed on their website, but they have them.

I personally don't care for foam filters, but I believe uni is probably the best amongst them.

We actually talked about switching to a Paul Turner pipe because I believe they are much better. I'm not sure if there is anything considered to be even better than that, but the FMF will do since we aren't looking to go all out with the motor anyway and it's a decent replacement for the stock exhaust. I'm hoping the money was better spent on the carb than on a PT pipe.
