hey stefan, only happen to come across your thread now or else i would have contacted you sooner. yes, i am surprised as everyone else that one of our newer generation manifolds have cracked. this is the first sr-series manifold since its release couple of years back that has encountered a cracking issue. we are currently shut for our new year and re-open on the 22nd. if you can PM me your name/shipping address..i can have a new manifold shipped out to you once we re-open. will need a little bit of time for fabrication though. i apologize for any inconvenience this may have caused you mate. yeah we have had cracking issues with a lot of our first generation manifolds in the past..this is no secret and we've always honored our warranty. all the hits on google threads are of old first generation units that had an issues with cracking. this is not a very common occurrence at all with our new manifold designs which have been out now for couple of years
