yep the manifold woulda cost $2000.00 if i woulda bought it. Then i woulda had to wait for it to be made. Ive got about 4-5hrs into the collector, and then maybe another 9-10hrs into the rest? i wasnt paying too much anttention to time. Im sure if i were to build another one, i could cut the time down by ALOT. but i dont think ill make anymore, this was kinda a pita.
