I have done so much research on both of these upgrades but it seems like all the websites selling this stuff are all the ones that are writing the reviews so it's had to believe what these reviews say. I want to replace the stock manifold and intercooler pipes but what are the best brands. I have been seriously looking at the AFe Bladerunner manifold and the MBRP Intercooler Pipes but its hard to get a straight answer whether or not they are the best. I would like to go with Banks but they won't come out with the Cummins 6.7L Manifold for a few years so I wanna know what is the next best thing. Anyone got any ideas?
