I was bidding on those manifolds. Somebody really wanted them. After paying more than $350 they still have to be repaired. I'm using the later version with water heat. I'd prefer to have heat sooner than is available from my thermostat. I always assumed the exhaust heat would leak and make noise. I may make the switch if I ever get my truck back from the engine builder.
