Improve your Infiniti's performance and acoustic profile with the Injen SES1997TT Performance Cat-Back Exhaust System. Engineered by the specialists in Pomona, CA, this true dual exhaust system replaces restrictive factory components with 60mm mandrel-bent 304 stainless steel tubing. This construction ensures the tubing maintains its diameter through every bend, providing smooth, unrestricted airflow that delivers dyno-proven gains of up to 14 hp and 16 lb-ft of torque.

The SES1997TT features an integrated upstream resonator with an internal X-pipe to balance exhaust pulses and eliminate drone, while dual JDM-style round mufflers provide a crisp, aggressive tone. Each system is 100% TIG welded and utilizes investment cast flanges for a precise, leak-free fit using factory mounting points. The system is finished with dual 4.5-inch titanium dual-wall rolled-burnt tips for a premium, high-performance aesthetic.
