The OEM design utilizes short, unevenly cast runners that force exhaust pulses to collide. This creates excessive back pressure and localized heat soak near the cylinder head. This turbulence drastically restricts scavenging capabilities at higher RPMs, preventing the engine from evacuating spent gases effectively. Over time, this thermal and fluid restriction limits power output and completely suppresses the aggressive exhaust note inherent to the 5.0L V8 architecture.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThese mid-length, high-flow exhaust headers are geometrically optimized to alleviate restrictive factory bottlenecks. Utilizing widened primary tubes, the system ensures laminar exhaust flow, minimizing exhaust pulse collisions and drastically lowering back pressure. This fluid dynamic improvement directly enhances cylinder scavenging, allowing the engine to breathe freely and ingest a denser air-fuel mixture. For naturally aspirated 5.0L V8 applications, expect a 7 to 10 percent increase in horsepower and torque. Supercharged M113K variants will achieve up to 15 percent gains due to the higher volume of expelled gases. The kit includes integrated downpipes designed for a custom weld-in installation, delivering a deeper, more aggressive resonance.\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;\"\u003e2003-2006 Mercedes Benz E-Class\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;\"\u003eM113 5.0L V8 (M113K Supercharged) \/ W211\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;\"\u003e302 hp \/ 339 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 \u0026amp; Fitment Notices\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eFits LHD and RHD vehicles\u003c\/li\u003e\n    \u003cli\u003eFor Mercedes-Benz SL55 AMG\u003c\/li\u003e\n    \u003cli\u003eFor Mercedes-Benz CLS55 AMG\u003c\/li\u003e\n    \u003cli\u003eFor Mercedes-Benz E55 AMG\u003c\/li\u003e\n    \u003cli\u003eFor Mercedes-Benz C55 AMG\u003c\/li\u003e\n    \u003cli\u003eFor Mercedes-Benz SL500 AMG\u003c\/li\u003e\n    \u003cli\u003eFor Mercedes-Benz CLS500 AMG\u003c\/li\u003e\n    \u003cli\u003eFor Mercedes-Benz E500 AMG\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eInstallation Note:\u003c\/strong\u003e Headers include downpipes and must be welded to the existing exhaust system.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eClearance Warning:\u003c\/strong\u003e W211 (E-Class) steering shaft interference is common; W220\/C215 (S\/CL) subframe clearance issues; R230 (SL) tight around transmission tunnel; W203 (C55 AMG) extremely tight engine bay.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLegal Notice:\u003c\/strong\u003e Off-road Certification.
