OK, so we tackled fuel and air going into the combustion chamber, now we need to get all of that air out of the engine. To help our LSX376 breathe easy, we ordered a pair of American Racing Headers long-tube headers. These bad boys are made out of 304 stainless steel, feature 3/8-inch flanges and massive 17/8-inch primaries complete with hand-ported inlets. The primaries merge into a large 3-inch Y-pipe collector and will be connected to our Banks 3-inch Monster exhaust system. Another bonus, these headers are made right here in the U.S.A., and will fit lowered trucks, so our Project Novakane won't be having any clearance issues.
