I was the first person to receive my bikeman pipe since I live right next to them. After about 6-700 miles it began to crack at the spring perch. I called neal up and told me to come right over and grab a new one. The new batch of pipes have been revised and now have a relief pressed in so it doesn't come so close to the bulk head support when mashing on it. I guess his was ground down for the durability kit and when they made the first pipes they forgot that so it sat alot closer. Awesome guys and warrantied it right away.
