On the supercharged \u003cstrong\u003eLSA\u003c\/strong\u003e powertrain, this restrictive chamber design creates parasitic exhaust backpressure, traps excess thermal energy upstream, and dulls the natural acoustic profile of the forced-induction V8.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eManufactured from corrosion-resistant \u003cstrong\u003e304 Stainless Steel\u003c\/strong\u003e, this axle-back kit improves gas evacuation using free-flowing mandrel-bent tubing and robust TIG welds designed to withstand severe thermal cycling. The integrated valve control mechanism gives drivers direct command over exhaust velocity and sound profile, switching between an aggressive straight-through path under boost and a refined profile for highway cruising without in-cabin resonance. Precision-engineered tip outlets ensure factory-spec clearance with the rear bumper valence.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eAxle-back exhaust assembly with integrated tip outlets\u003c\/li\u003e\n  \u003cli\u003eValve control hardware module\u003c\/li\u003e\n  \u003cli\u003eMounting hardware kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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 Cadillac CTS-V\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;\"\u003eLSA 6.2L Supercharged V8 \/ Sigma II (V2)\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;\"\u003e556 hp \/ 551 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;\"\u003eB-EXT-MD023-2, 14 15 CTSV V2 Rear Bumper Exhaust\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2009-2014 Cadillac CTS-V 6.2L Supercharged V8 (Sedan, Coupe, Wagon)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the Sigma II CTS?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2009-2014 Cadillac CTS equipped with the \u003cstrong\u003eLSA\u003c\/strong\u003e 6.2L engine. \u003cstrong\u003eThis unit does not fit base CTS models equipped with 2.8L, 3.0L, or 3.6L V6 engines.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eWhat critical steps are required during installation?\u003c\/h4\u003e\n\u003cp\u003eVerify hanger alignment, flange bolt patterns, and tip clearance before final torquing to OEM specifications, and inspect all joints for exhaust leaks post-installation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Cadillac Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to withstand the demanding thermal and flow characteristics of the supercharged LSA engine, this system balances raw American muscle presence with refined, drone-free highway operation.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":68046656995576,"sku":"DS-ECGRODEHS","price":649.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/axle-back-exhaust-for-cadillac-cts-v-2009-2014-6-2l-1.jpg?v=1794267901","url":"https:\/\/performancechiptuning.com\/de\/products\/axle-back-exhaust-for-cadillac-cts-v-2009-2014-6-2l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
