This design creates significant backpressure, which forces the L15CA turbocharger to work harder to evacuate spent gases, leading to higher exhaust gas temperatures (EGTs) and slower boost response. Additionally, the factory mild steel construction is prone to oxidation over time, and the muted tone fails to provide the mechanical feedback necessary for a performance-oriented driving experience. These flow limitations become even more pronounced on vehicles running increased boost pressures or aftermarket ECU calibrations.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis catback system provides a high-flow path using premium T304 stainless steel, offering superior resistance to heat-cycle fatigue and road salt corrosion. The 3-piece configuration features precision mandrel-bent piping to ensure a constant inner diameter through every bend, minimizing turbulence and maintaining high exhaust gas velocity. A specifically tuned resonated mid-pipe is integrated to filter out high-frequency rasp and low-end drone, delivering a refined yet aggressive note suitable for daily driving. Each joint is hand TIG-welded for maximum structural integrity, and the system terminates in dual 4-inch burnt slant-cut tips. By reducing pumping losses, this system allows the small-displacement turbo engine to breathe more efficiently throughout the powerband.\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;\"\u003e2022-2025 Acura Integra\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;\"\u003eL15CA \/ DE4\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;\"\u003e200 hp \/ 192 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\u003e2022-2025 Honda Civic Si FE1 1.5T\u003c\/li\u003e\n  \u003cli\u003e2022-2025 Acura Integra 1.5T DE4\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Acura Performance Standard\u003c\/h3\u003e\n\u003cp\u003eThis exhaust system is engineered for the enthusiast who demands a balance of daily-drivable civility and track-ready flow.
