The 3.3-litre twin-turbo V6 under the bonnet of the new Kia Stinger is a great engine, but it doesn’t exactly shout it intentions from the rooftops.

Kia Australia has been upfront about its intentions to rectify this with an optional exhaust system and has now revealed the exhaust will cost $2659.99 fitted with the first examples expected to be available prior to Christmas 2017.

Melbourne-based company Lumens has been responsible for the development work at the behest of Kia Australia, with the result being an electronically-controlled bi-modal system that bypasses the mufflers for a louder, purer exhaust note.

In other news Kia Australia CEO Damien Meredith dropped a hint that a more potent Stinger could be on the way: “You can assume that what we’re doing with Stinger doesn’t stop with a V6 twin-turbo, but we’ll have to wait and see.”

Stinger boss Albert Beirmann has made no secret of his wish to develop a faster, more focused version of Kia’s new sports sedan, though there are currently no plans for that car to offer more than six cylinders.
