Message My Z came with AMS manifolds (likely why it has a leak now). I need to replace them and I want to get something better. However, $3,000 for MSP's is out of the question. Should I look at a different brand (Ash Spec?), or spend the money having a machine shop fix the poor quality of the AMS manifolds? The car is running z1 525's.

If I do have a machine shop fix the AMS could they get thermal coated or would that likely just cause more cracks because of the trapped heat.
