its louder than the hrc pipe but not stupid loud, it has a really good tone to it. the throttle response is great but my jetting is off.

im running the stock hrc jetting (162) I have a jet kit on the way with 160 to like 205, It wont hook up for anything right now so I dont know how fast it really is.

the cold may also be hurting my jetting (my pipe turned a dull pink so I put it up)
