Powerbomb w/ Powercore 4 Exhaust?

[Mr Powell]

How well do you like them? I found a good deal on a used set. The bike is getting that, jet kit and intake for now. Maybe a CDI upgrade, but other then that. Thats about all it will ever get.

Is it really loud?

I have it it. It is loud, but not too loud, and has a nice, strong growl to it. Powerwise is very nice. It gives you a real snappy powerband, and has alot of punch to it, especially when compared to stock! Overall I am very happy with it.

I would get the powerbomb and factory 4 if you are getting one from fmf

but I prefer Yoshimura

[CHEVYZ]

I don't like yoshimira at all. I have never been impressed with them, as it seems like every bike I have ever run against with yoshimira has been spanked by myself with less mods... different pipe of course.
