yep they won't crack, just pop out on the front cylinder. sold 3 sets and have it on my personnal ride and on landings the front pipe will come out of head. talked with them a few times on there problem and they want me to send in the pipes so they can put a hook on to put a spring on it. the way they have the spring it doesn't pull the pipe up to the head good. basically they welded on the hook on the wrong side. so they want us to be down for a few weeks while we send at our expense the front head pipe out. piss poor customer service at best. fix is either put a hose clamp around and another spring or weld a hook on your self and add a spring. no other problems yet, but be prepared to do everything yourself with there piss poor customer service idea's.
