Need Exhaust???

[08BLACK450R]

I am installing a HCII in my new 08' ER and i need exhaust. Can still make power with just a HRC Head pipe an no arrestor or do I have to do full exhaust. If i did a full system i was thinking DASA, Curtis Sparks, or Yoshi... Does anybody have any suggestions.

i have a stage 2 and run a stock exhaust with nothing done to it and its a noticable difference. haha

you dont have to do anything lol but you just wont get all the power you could outa the HCII but there will be a difference...if you have the money id DEF. sugest getting a full exhaust! the ones you mention are all good DASA,curtis and rossier(sp) are at the top of the list,imo DASA would be the best way to go but everybody has they're own opinion.
