The short, unevenly sized runner layout causes exhaust gas pulses to collide directly outside the cylinder head ports. This design generates substantial backpressure, traps excess heat in the cylinder heads, and inhibits thermal evacuation—severely restricting high-RPM horsepower on naturally aspirated \u003cstrong\u003eLT1\u003c\/strong\u003e engines and accelerating heat soak on supercharged \u003cstrong\u003eLT4\u003c\/strong\u003e applications.\u003c\/p\u003e\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered with extended, mandrel-bent \u003cstrong\u003eT304 stainless steel\u003c\/strong\u003e primary runners, these long tube headers direct exhaust pulses smoothly into high-velocity merge collectors.
