K-Tuned Big Tube Honda K-Swap Manifold Header Exhaust

• Engine modifications like bigger cams, ported cylinder heads, increased compression ratio and/or increased displacement all breathe heavier, so using a small header on these engines just doesn't make any sense. 
• A bigger header will increase efficiency by opening up the exhaust path, offering reduced restriction and allowing exhaust gases to flow out of the engine faster, which in turn will make more power. 
• Our Big Tube Header features a proven stepped 4-2-1 Tri-Y design with extremely smooth merge transitions that improve exhaust flow. 
• We started with 48mm primaries that progressively move into 50mm, then 54mm secondaries and finally a 75mm or 3 inch exit. 
• It is assembled with mandrel bent, T304 stainless steel tubing and is beautifully back purge tig welded to keep the welds super clean, ensure proper penetration and weld strength. 
• We decided to leave the header exit unfinished, giving the installer open options on what is used for the final connection to the exhaust piping. 
• Please note that a flex pipe or a donut flange with spring bolts must be used for proper installation.
