On a forced-induction LSA engine, this restriction traps heat near the exhaust valves, increasing cylinder head temperatures and hindering the supercharger's volumetric efficiency. The OEM assembly is prone to heat soak and uses inferior grade steel that degrades over time under the high thermal loads of a 550+ horsepower application, resulting in parasitic power loss and a muted acoustic profile.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered for maximum gas throughput, this system is constructed from high-grade stainless steel featuring computerized mandrel-bends to ensure a constant internal diameter. By eliminating the bottlenecks found in OEM crush-bends, the system maintains laminar flow and reduces turbulence across the 2.5-inch OD main piping. The TIG-welded CNC machine flanges provide superior resistance against warping and high-pressure leaks. The dual straight-through perforated core mufflers utilize high-density packing to deliver an aggressive, deep tone while minimizing drone. The assembly is finished with 4.5-inch double-walled diagonal cut tips for improved heat dissipation at the rear fascia.\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;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2011-2014 Cadillac CTS-V Coupe 2-Door\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e6.2L LSA V8 \/ Sigma II\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e556 hp \/ 551 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2011 Cadillac CTS V Coupe 6.2L\u003c\/li\u003e\n  \u003cli\u003e2012 Cadillac CTS V Coupe 6.2L\u003c\/li\u003e\n  \u003cli\u003e2013 Cadillac CTS V Coupe 6.2L\u003c\/li\u003e\n  \u003cli\u003e2014 Cadillac CTS V Coupe 6.2L\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Cadillac Performance Standard\u003c\/h3\u003e\n\u003cp\u003eDesigned specifically for the LSA-powered V-Series, this exhaust upgrade focuses on reducing the thermal signature of the exhaust stroke.
