getting a new exhaust

I really like the hmf utility on my rubi. Sounds good and gave me good power with jet kit and k&n filter. It really woke my bike up, throttle response is a lot better. I used to not be able to pop a wheelie due the extra weight of my bumper and winch on the front, but now with the pipe, filter and jet kit it pops up on small inclines when I pin the throttle. However its not for those who don't like it loud.

I'm not sure what kind of power and how loud the penland is, but from what I understand the utility is supposed to give you the most power and noise...

thanks alot the utility is cheaper i think ima get it
