New MAP short runner manifold cracked
So I recently picked up a short runner manifold from MAP about two months ago while my car was down and I have about 3k miles on the manifold and its already cracked between the runners where the two meet. Anyone else have this issue yet? I hope they will replace it for free.

I am pretty sure it only has a one year warranty because i asked what the warranty was before i bought one. I was told that they do not lifetime warranty this manifold because they are not built in house.

I had this same issue, it actually cracked in multiple places. MAP resolved the situation very quickly and easily for me without any hassle at all. I ended up upgrading to the their long runner version in fear of this one cracking again.

This is the first issue I've heard of with the Evo X version, and as was mentioned above we will certainly take care of you 
The Evo 8 & 9 manifolds had a few issues with the anti-lag provisioning as the manifold was designed to work with Evo 4-9, however, when the anti-lag ports were blocked off it caused heat to build up and the potential for cracking. The Evo 8 & 9 short runner manifolds no longer have the anti-lag provisioning and we haven't had an issue since

Alot depends on how they are used and the heat cycles they go through. Water hitting them when they are hot is obviously bad and on the Evo X that vent is hovering right above it. At a racetrack where it sees crazy high temps you will find out really quickly if there is any stress or tension between two welded parts. Make sure you have the Downpipe to engine block bolt in place as well as the turbo compressor side bracket bolt with no side to side tension since that can cause issues over time. Probably that one bolt that mounts the turbo from below is semi optional, that was missing from the factory on my car.
