Save for its range of hypercars and the LT series of models, road-going McLarens don’t sound as exhilarating as a Ferrari or Lamborghini does. Not even the aftermarket scene helps, especially because it’s a pain to find the ideal exhaust system, a unit both loud and free of drone. Happily, however, Larini Systems knows better.
The UK-based company offers a wide selection of exhaust systems for McLaren models, from the MP4-12C to the 540C and even the 675LT. On this occasion, however, a 570S is the focus of the story. Specifically, the sound it produces with Larini-developed sports catalytic converters.

Dubbed by Larini “maybe the greatest exhaust video of all time,” the 6-minute clip at the end of this story is a testament to how a tuning outfit can change the aural identity of a car to a great extent. For reference, the second clip at the end of this story features a stock McLaren 570S.

$2,406.25 on top of the starting price of a McLaren 570S ($184,900) buys you the Larini Sports Catalysts pack. As you can hear from Mike Tornabene’s exhaust video, the aural delight was turned all the way up to 11. From an enjoyable yet sedated hubbub in stock form, this Macca morphs into an intoxicating white knuckle ride thanks to Larini’s know-how.

As per the manufacturer, the 300-cell sports catalytic converters offer “near unopposed gas flow. The resulting increase in flow rates - with a modulation of backpressure, allowing the engine to breathe and perform better.” Other than a slight power increase without any emissions-related drawback, the cats retain McLaren’s OEM connections for the lambda/heat probes.
