This rough internal casting causes exhaust reversion, uneven cylinder scavenging, and severe thermal retention. Under repeated thermal cycling and increased boost pressures, the brittle OEM iron structure is prone to hairline stress cracking, warping at the head flange, and choking high-RPM volumetric efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed from mandrel-bent 16-gauge (1.5mm) \u003cstrong\u003e304 stainless steel\u003c\/strong\u003e, this tubular assembly incorporates smooth 1-5\/8 in.
