So i have seen a couple of improved stock vipers and they had the powervalves removed... What are the benefits or are there any?
you have full open exhaust doesnt need to wait for servo to open it .....but u need to have a high engagement because of the big duration..si think they doesnt remove them they just hook them open

not good for trail ridding
They are usually running big-bores or really wild porting. Don,t even consider this on a trail sled as your bottom end will vanish.

Thanks guys just wasnt sure on this...been looking at a few improvers that had this done. So you can remove the servo and cables correct?
