Lookin for feedback about which aftermarket pipe to add to my X. What's good, What's not? I don't want to spend and huge amount, But i don't want a P.O.S either. I was thinkin procircuit.. No guys this is not for adding performance to the bike, I just need a good sound.. Stock is too quiet. plus I wanna rejet this w\ a pipe because the X comes factory way too lean. any ideas?
