From an engineering standpoint, press-bent tubing features localized cross-sectional collapses that disrupt laminar exhaust velocity and produce excessive backpressure. Coupled with high-resistance internal baffles, this restriction impedes cylinder scavenging on the \u003cstrong\u003e2AZ-FE\u003c\/strong\u003e 2.4L engine, trapping thermal energy in the cylinder head and dulling throttle response. Furthermore, factory mild steel is prone to road-salt oxidation, flange corrosion, and premature joint failure over time.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eFabricated from high-grade polished T-304 stainless steel, this performance cat-back system replaces restrictive factory routing with smooth, mandrel-bent piping to maintain uniform cross-sectional volume throughout every bend. Precision TIG welding and heavy-duty pre-welded hangers ensure exact alignment with factory mounting points for a bolt-on installation without chassis modification. By eliminating restrictive internal chambers in favor of a straight-through core design, this system significantly accelerates exhaust gas velocity, lowers backpressure behind the catalytic converter, and delivers a clean, resonant acoustic profile engineered specifically for the \u003cstrong\u003e2AZ-FE\u003c\/strong\u003e platform.\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;\"\u003e2005-2010 Scion tC\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;\"\u003e2AZ-FE \/ ANT10\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;\"\u003e161 hp \/ 162 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-CAT1237\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2005-2010 Scion tC Base Hatchback 2-Door 2.4L L4 (2AZ-FE)\u003c\/li\u003e\n  \u003cli\u003e2007-2008 Scion tC Spec Hatchback 2-Door 2.4L L4 (2AZ-FE)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the ANT10 tC?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2005-2010 Scion tC equipped with the 2.4L \u003cstrong\u003e2AZ-FE\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this cat-back exhaust system trigger a Check Engine Light (CEL)?\u003c\/strong\u003e\u003cbr\u003e No, the system installs downstream of the factory catalytic converter and secondary oxygen sensor, preserving factory emissions compliance without triggering diagnostic trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Scion Performance Standard\u003c\/h3\u003e\n\u003cp\u003eDesigned specifically for the Japanese sport compact platform, this exhaust optimizes thermal evacuation and acoustic resonance to unlock the full mechanical potential and aggressive sound of your high-revving coupe.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50608335552760,"sku":"DS-EL77P1R87","price":257.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/cat-back-exhaust-for-scion-tc-2005-2010-2-4l-1.jpg?v=1790092302","url":"https:\/\/performancechiptuning.com\/fr\/products\/cat-back-exhaust-for-scion-tc-2005-2010-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
