While effective at dampening engine noise to passenger-car targets, this stock layout induces parasitic exhaust backpressure. This disrupts post-combustion cylinder scavenging on the \u003cstrong\u003e5.7L HEMI Eagle\u003c\/strong\u003e, trapping residual exhaust heat in the cylinder heads and blunting throttle response across the midrange power band.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement cat-back system routes exhaust gases through uniform, mandrel-bent aluminized steel piping coated with manganese for sustained thermal and oxidation resistance. Eliminating restrictive internal baffles in favor of free-flowing straight-through muffler internals maximizes laminar gas velocity and improves pulse scavenging. Integrated pre-welded hangers mate directly with factory rubber isolators, ensuring exact bumper-valence tip alignment without requiring cutting, heating, or custom fabrication.\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; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2009-2014 Dodge Challenger\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003e5.7L HEMI Eagle\u003c\/strong\u003e \/ \u003cstrong\u003eLC\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e372-375 hp \/ 400-410 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\u003cstrong\u003eSPT-CAT1379\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2009-2014 Dodge Challenger R\/T 5.7L V8\u003c\/li\u003e\n  \u003cli\u003e2012-2014 Dodge Challenger R\/T Classic 5.7L V8\u003c\/li\u003e\n  \u003cli\u003e2014 Dodge Challenger R\/T Shaker 5.7L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the LC Challenger?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2009-2014 Dodge Challenger equipped with the \u003cstrong\u003e5.7L HEMI Eagle\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this cat-back system trigger a Check Engine Light (CEL)?\u003c\/strong\u003e\u003cbr\u003e No, because this assembly bolts downstream of all factory catalytic converters and heated oxygen sensors, OBD-II emissions readiness monitors remain fully unaffected.\u003c\/p\u003e\n\n\u003ch3\u003eThe Dodge Muscle Caliber\u003c\/h3\u003e\n\u003cp\u003eHigh-displacement pushrod V8 platforms demand unrestricted thermal evacuation to perform under load.
