I wasn't expecting a huge performance improvement, and it was right of me to believe that.

It seems like 30-55mph is quicker though. Definitely less effort needed from the engine to get up to 80. Hits the speed limiter quicker. Really nothing huge, but a little improvement is good.

The sound....well...is it suppose to sound like a oversized harley? I don't mind it, I don't know if I like it a lot yet. We'll see.

Overall, I'm happy, and it was worth the $100.

Thanks Chankle for giving me that website, they're good people. I don't have the website anymore so i can't post their link.
