Holy $hit batman!
Finally got a chance yesterday evening to take the bike out for a test run and I mean to tell you, the beast within has awakened. Between the filters and the laser slip-on, it just plain rips! I lofted the front wheel a couple times just gettin' on it.
Yes, it does make the bike much louder, but so far, I like it - sounds like a real hotrod.
I remember when I put the pipe on, it was noticibly quicker, but after the filters, the difference was more drastic.
If you like performance, I highly recommend it.
...just my 2 cents.
