Borla Kia Stinger GT 3.3 T-GDI Cat-back S-Type

Borla manufactures performance exhaust systems in the USA using T304 stainless steel. Its three sound levels are a defining feature: restrained Touring, more assertive S-Type and the most aggressive ATAK.

This gives drivers a choice between a subtle everyday soundtrack and a stronger performance character. Borla cat-back systems cover passenger cars and pickup trucks, with sound-level availability depending on the vehicle application.

ATAK technology uses multiple tubular cores whose shapes and perforations are selected for the intended exhaust note. Computer modelling allows individual frequencies to be tuned rather than simply raising overall noise levels. Borla silencers are developed for specific applications so their sound complements the particular vehicle.

History and development. Alex and Alyse Borla developed a business that began making exhausts in 1978, initially for classic Rolls-Royce and Ferrari cars. Its activities subsequently expanded to mainstream performance vehicles, trucks and racing applications.

The business today. Borla continues to design and manufacture in the United States, with facilities in California and Tennessee. Alongside complete exhaust systems, it offers universal components and products for specialist builds. In-house development and distinct sound levels remain central to a range sold both domestically and internationally.
