I bought my 01 929 non erion edition with and erion pipe and i have never heard of that untill i got this bike, Is this pipe any good? also (sorry im new) will my bike run any better performance wise withought that piece between the header and pipe? probably dumb ?'s but i am new and really want to learn. I have ridden many bikes but i love my 929

 

if you have a full exhaust system that exhaust valve was removed... if its a slip on it will run better with the vavle out for stunt riding. if you street ride keep it in.. erion is a good pipe. (dont worry)
