Description

The Injen SES1390TT cat-back exhaust system is engineered by Injen Technology to deliver enhanced performance and an aggressive sound for specific Hyundai Genesis Coupe models. Constructed from 60MM mandrel-bent 304 stainless steel tubing, this system ensures consistent diameter and smooth, unrestricted airflow throughout its entire length. The exhaust features dual round mufflers and a 4.0” burnt titanium quad-tip design, contributing to both exceptional sound quality and performance gains. The system is hand TIG welded and handcrafted in the USA, emphasizing strength, durability, and show-quality aesthetics with embossed stainless steel mufflers. This exhaust system has demonstrated dyno-proven gains of up to 8 horsepower and 9 lb-ft. of torque. It is designed for a direct fit on the 2010 - 2015 Hyundai Genesis Coupe 3.8L V6. The package includes the exhaust system itself and comes with a Limited Lifetime Warranty from Injen Technology.
