Kia Stinger GT CK V6 3.3 TT Valved Exhaust System (2018-2023)

The Kia Stinger GT V6 3.3 biturbo exhaust in detail.

The Stinger GT relies on a 3.3-liter V6 with two turbos and direct injection: 370 hp and 510 Nm, generous thrust from the mid-range and real ease in picking up a car of this size. It is a grand touring engine, generous and supple, that Kia nevertheless dressed in an exhaust designed for serenity, even if it meant erasing all sound.

Unleashed, this twin-turbo V6 has a round, powerful voice, with a slightly gravelly grain as the turbos build boost. With the valves open, the valved Rog cat-back gives the Stinger a more present idle, full-bodied acceleration and pick-up that punctuates every corner exit; with the valves closed, it becomes the quiet highway grand tourer again.

The page covers the Stinger GT CK from 2018 to 2023, built to your VIN and checked before production. Fitting is done without welding, with clamps and gaskets, in about two hours, and the valves follow the factory control if the car has it, or the Rog remote, with its box in the trunk.

Under the “Manifold” option, the page also sells the primary downpipe that follows the turbos and carries the catalytic converter. Without an ECU remap, it only adds sound and a little lightness; it is the map that turns it into power, with no Stage 2 figure published for this V6. On this Korean grand tourer designed to eat up the miles, the 200-cell downpipe is the one that keeps emissions control, the 100-cell will be accepted or not depending on the vehicle and your country’s rules, and the decat version is reserved for track use, far from the long journeys the Stinger was designed for. At the rear, the Stinger GT’s four round tips keep their layout, with 304 stainless steel or titanium, around 40% lighter and offered in three colors, mainly changing the weight and the tone.
