# **All-New STILLEN Cat-Back Exhaust System for the Kia Stinger GT 3.3L V6 Twin Turbo**

STILLEN is proud to announce the release of the [STILLEN Cat-Back Exhaust System for the 2018-2019 Kia Stinger GT 3.3L V6 Twin Turbo](https://stillen.com/products/2018-2019-kia-stinger-gt-cat-back-exhaust-awd-rwd-3-3l-twin-turbo-504330), compatible with both AWD and RWD configurations. The Kia Stinger GT is a genuinely impressive performance sedan, offering acceleration that outpaces a Ford Mustang GT and a feature set that directly challenges the European sport sedan segment. With the STILLEN cat-back exhaust in place, the Stinger GT's performance story gets even better.

### **Dyno-Proven Performance Gains**

Tested on STILLEN's in-house DynoJet dynamometer in Costa Mesa, CA, the [STILLEN Kia Stinger GT Cat-Back Exhaust](https://stillen.com/products/2018-2019-kia-stinger-gt-cat-back-exhaust-awd-rwd-3-3l-twin-turbo-504330) produced a maximum increase of +30 horsepower and +30 lb-ft of torque over the factory exhaust system. The gains are real, repeatable, and felt throughout the power band.

For those looking to maximize their Stinger GT's performance potential, pairing this cat-back exhaust with the STILLEN Kia Stinger GT Hi-Flow Air Intake results in a combined gain of up to +40 horsepower and +40 lb-ft of torque, making the two-piece combination one of the best bang-for-the-buck performance upgrades available for the platform.
