The stock log-style manifolds create high exhaust gas back pressure, increasing cylinder head temperatures and inducing heat soak under heavy load. This bottleneck chokes the supercharger's efficiency, limiting volumetric flow, capping horsepower at higher RPMs, and heavily muffling the distinctive AMG V8 exhaust note.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eUpgrading to these mid-length, high-flow headers fundamentally alters the exhaust dynamics of the M113K engine. Featuring wider primary pipes and optimized collector geometry, this system substantially reduces back pressure and promotes superior exhaust scavenging. Evacuating spent gases faster decreases cylinder temperatures and minimizes pumping losses. This allows the supercharged engine to breathe freely, translating to significant performance gains—up to a 15 percent increase in horsepower and torque. The kit includes integrated downpipes to complete the transition. \u003cem\u003eNote: Installation requires welding to your existing exhaust system and custom fabrication to navigate W220 subframe clearance issues.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2001-2006 Mercedes Benz S-Class (S55 AMG)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eM113K 5.4L Supercharged V8 \/ W220\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e493 hp \/ 516 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eFits LHD and RHD vehicles\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz S55 AMG (W220) → Note: subframe clearance issues\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz CL55 AMG (C215) → Note: subframe clearance issues\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz SL55 AMG (R230) → Note: tight around transmission tunnel\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz E55 AMG (W211) → Note: steering shaft interference common\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz C55 AMG (W203) → Note: extremely tight engine bay\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz CLS55 AMG\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz SL500 AMG\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz CLS500 AMG\u003c\/li\u003e\n  \u003cli\u003eMercedes-Benz E500 AMG\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Mercedes Benz Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered specifically for high-output European applications, this exhaust modification delivers the uncompromised power and aggressive exhaust signature mandatory for a modified AMG vehicle.
