The flex pipe would still be required after this header and before the MBRP exhaust. What this header eliminates is the stock cat. The flex starts after this header and snakes up over the front sub assembly and then joins to the aftermarket exhaust. You would not be able to attach this header directly to the exhaust without bumping in the the front assembly cross member and to go underneath it would make it lowest point between the tires and in danger of road damage.
