Which is the best exhaust manifold?
 

Hey guys trying to decide what manifold to get for my 5.9 cummins. I havent done anything too crazy so far to the motor. I have a banks big hoss tuner I'm not extremely satisfied with but happy it works for $40 bucks off craigslist. I've got a 4" MBRP no muffler exhaust. Also have EGT, trans temp, and fuel pressure gauges waiting to be installed after the manifold is bought and placed. I think I've narrowed it down to these 2: The AFE bladerunner or the BD Diesel 24V Exhaust Manifold? Any help would be greatly appreciated. thanks in advance

Between those two, BD for sure. The BD is a 3 piece, which will help prevent cracking. Even the best one piece is prone to cracking.

ok thanks, I wasn't sure if the 3 piece would eventually get to where it wouldnt expand and contract and crack anyways. The AFE has the solid bar support and i wasnt sure if that would be better for the long run. thanks for the input
