I've been looking at the yoshimura slip on and it looks like a pretty good pipe. does anyone on here have one? good power gains? loud? good sound? easy installation? good directions/jetting help? any info on this pipe will help. thanks.

 

i dont have one but my friend does and he seems to really like it the power gains are not very big but noticable and sound is amazing install was pretty easy from what i know but i really do not know about the jetting detials
