Over time, stock piping suffers from thermal fatigue and corrosion at the stamped flanges. Furthermore, factory neck-downs and internal baffle chambers disrupt laminar exhaust flow, causing excessive exhaust backpressure that restricts the high-RPM breathing capacity of the VTEC crossover.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis system replaces downstream restrictions with full \u003cstrong\u003eT-304 stainless steel\u003c\/strong\u003e construction to eliminate corrosion failure and optimize thermal management. Featuring uniform 2.25-inch mandrel-bent tubing, this direct-fit configuration maintains constant inner diameter geometry through every radius, reducing turbulence and pumping losses. A free-flowing straight-through muffler dampens harsh frequencies without choking flow, terminating in an aggressive 4.5-inch polished tip. Precision TIG-welded OE-style hangers and factory-pattern flanges guarantee a true bolt-on installation using OEM mounting positions without requiring cutting or re-welding.\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;\"\u003e2004-2008 Acura TSX\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\u003eK24A2\u003c\/strong\u003e \/ \u003cstrong\u003eCL9\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;\"\u003e200-205 hp \/ 164-166 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;\"\u003eN\/A (Replaces factory cat-back assembly)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2004 Acura TSX Base Sedan 4-Door 2.4L 2354CC l4 DOHC\u003c\/li\u003e\n  \u003cli\u003e2005 Acura TSX Base Sedan 4-Door 2.4L 2354CC l4 DOHC\u003c\/li\u003e\n  \u003cli\u003e2006 Acura TSX Base Sedan 4-Door 2.4L 2354CC l4 DOHC\u003c\/li\u003e\n  \u003cli\u003e2007 Acura TSX Base Sedan 4-Door 2.4L 2354CC l4 DOHC\u003c\/li\u003e\n  \u003cli\u003e2008 Acura TSX Base Sedan 4-Door 2.4L 2354CC l4 DOHC\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the CL9 TSX?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2004-2008 Acura TSX equipped with the \u003cstrong\u003eK24A2\u003c\/strong\u003e 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 installs entirely aft of the factory catalytic converter and secondary O2 sensor, it retains complete emissions compliance and will not trip DTCs.\u003c\/p\u003e\n\n\u003ch3\u003eThe Acura JDM Caliber\u003c\/h3\u003e\n\u003cp\u003eTuned specifically for the high-revving characteristics of the naturally aspirated K-series platform, this exhaust provides the unchoked flow needed to unlock higher mid-range torque and a crisp, aggressive VTEC crossover without highway drone.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50622356160760,"sku":"DS-E9NNLC71J","price":350.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/cat-back-exhaust-for-acura-tsx-2004-2008-2-4l-1.jpg?v=1790263517","url":"https:\/\/performancechiptuning.com\/es\/products\/cat-back-exhaust-for-acura-tsx-2004-2008-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
