Under high-load operation, these stock pinch points cause thermal heat soak, restrict exhaust scavenge efficiency, and create turbulent reversion directly downstream of the downpipe. Over time, mild steel OEM hardware and thin-wall tubing also succumb to thermal fatigue and road-salt corrosion.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eFabricated from heavy-gauge stainless steel, this system utilizes continuous mandrel-bent tubing to maintain uniform internal diameter through every curve, maximizing laminar flow. Robotic TIG welds secure the pre-positioned OE-style hangers and precision-stamped flanges directly into place for rigid alignment with stock chassis mounting points. Designed as a bolt-on upgrade, it lowers exhaust backpressure without requiring cutting or welding, handling the high exhaust gas temperatures (EGTs) generated by aggressive boost targets.\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;\"\u003e2003-2005 Dodge Neon\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;\"\u003e2.4L Turbocharged I4 (A853) \/ PL Chassis\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;\"\u003e215-230 hp \/ 245-250 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;\"\u003eSPT-CAT1115\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2003 Dodge Neon 2.4L\u003c\/li\u003e\n  \u003cli\u003e2004 Dodge Neon 2.4L\u003c\/li\u003e\n  \u003cli\u003e2005 Dodge Neon 2.4L\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the PL Neon?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2003-2005 Dodge Neon equipped with the \u003cstrong\u003eA853\u003c\/strong\u003e 2.4L engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this cat-back trigger a Check Engine Light (CEL)?\u003c\/strong\u003e\u003cbr\u003e No, because this system bolts downstream of the factory catalytic converter, the primary and secondary O2 sensors remain undisturbed.\u003c\/p\u003e\n\n\u003ch3\u003eThe Dodge Performance Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle hard launches and high thermal duty cycles, this system delivers the aggressive exhaust acoustic profile and structural resilience demanded by high-output turbocharged Dodge platforms.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50607692579064,"sku":"DS-E1JQR3B9S","price":336.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/cat-back-exhaust-for-dodge-neon-2003-2005-2-4l-1.jpg?v=1790091428","url":"https:\/\/performancechiptuning.com\/fr\/products\/cat-back-exhaust-for-dodge-neon-2003-2005-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
