Show original supplier description
The ARK Performance downpipe system is crafted for enhanced exhaust flow and performance. Constructed from durable T304 stainless steel with a 2.5-inch diameter, this bolt-on system is designed to replace the stock catalytic converter, allowing your engine to breathe more freely. This downpipe is compatible with both Rear-Wheel Drive (RWD) and All-Wheel Drive (AWD) models of the 2018-2023 Kia Stinger 3.3T and the 2019-2026 Genesis G70 3.3T. The installation is straightforward, utilizing an all bolt-on design. It comes with two Type B gaskets for the rear flanges, and it is recommended to use your OEM or stock gasket for the flanges facing the engine. Included hardware consists of 4 bolts, 4 nuts, 4 small bolts, and 4 nuts. **Disclaimer:** This product is intended for off-road and racing use only. It replaces the stock catalytic converter and may not be legal for highway use on pollution-controlled vehicles. Use is restricted to racing vehicles that will never be registered or licensed for highway use. Purchase in California is prohibited. A 'Racing Use Only Waiver Form' must be completed, signed, and emailed to ARK Performance to finalize the purchase, attesting to the intended off-road or racing application.
