How is the power?? Was it a noticeable gain over the stock peashooter stinger?

you will notice quite a noticable improvement with the insert, but then again, you should really do all the "free" mods in conjunction with the insert. All combined, the bike is VASTLY better than stock and basically a necessity.

The other option if noise isn't an issue is to pull the baffle inserts altogether. The bike can't breath with the stock inserts so just about anything other than stock is an improvement.
