Borla Exhaust System Kit

Borla Exhaust System Kits: Engineered Sound, Real Performance

When enthusiasts talk about aftermarket exhaust, Borla is one of the first names to come up — and for good reason. Borla Performance Industries has spent decades pioneering exhaust technology, and their Exhaust System Kits represent the pinnacle of that work. These aren't generic bolt-ons; each kit is engineered specifically for the vehicle it fits, balancing sound character, flow efficiency, and long-term durability in a way that few competitors match.

Cat-Back Systems: The Full Transformation

The flagship of Borla's exhaust system kit lineup is the Cat-Back™ — a term that, notably, Borla itself pioneered. A Borla Cat-Back™ exhaust replaces the entire stock system from the catalytic converters back to the tips, delivering the most dramatic upgrade in sound by incorporating ultra-smooth mandrel bends, X-Pipe technologies, precise pipe diameter specs, and other characteristics that shape the exhaust note. The result is a fundamentally different driving experience every time you turn the key.

Three Distinct Sound Technologies — One for Every Driver

What sets Borla's exhaust system kits apart from the competition is the ability to choose your sound signature. Borla Cat-Back™ systems are available in three sound technologies — ATAK®, S-Type, and Touring — each with their own distinct volume and character. Understanding the difference is key to choosing the right kit:

• ATAK® — ATAK exhaust systems produce the highest decibel levels in the Borla line. This is Borla's most aggressive offering, purpose-built for drivers who want a raw, race-inspired exhaust note at every throttle input.
• S-Type — The S-Type option offers a slightly tamer, race-bred sound. It's the sweet spot for enthusiasts who want serious performance character without overwhelming cabin noise on daily commutes or highway cruises.
• Touring — Drivers who prefer a mild growl that's just a bit more aggressive than stock can choose Borla Touring sound. It's the understated choice — refined, deeper, and noticeably better than stock without calling attention at every stoplight.

Patented Technology Under Every Kit

Borla exhaust system kits aren't just pipes and mufflers bolted together — they incorporate genuine engineering innovations. Borla's patented SwitchFire™ design completely eliminates the turbulent center intersection of a standard X-Pipe, truly blending combustion pulses from both sides of the engine via breakthrough Polyphonic technology, resulting in a more aggressive sound and improved power. Additionally, Polyphonic Harmonizers use the same dynamics as organ pipes to deliver tuned, harmonious sound.

Built to Last: Materials & Construction

Borla pioneered the use of high-quality austenitic stainless steel in exhaust manufacturing over 30 years ago. Every exhaust system kit benefits from this legacy. The strength of the welds, precision fit of the slip joints, smooth high-flow mandrel bends, and austenitic stainless steel construction — superior to 409 or aluminized steel — all ensure top performance through the most grueling conditions. These systems are also fully compatible with modern vehicles utilizing exhaust valves to conserve fuel and provide cockpit control of driving modes and volume.

Bolt-On Installation, Million Mile Confidence

Borla systems are designed to be completely bolt-on to your vehicle — factory locations are utilized and all necessary installation hardware is included in the kit. Once installed, every system is backed by Borla's legendary Million Mile Warranty, a testament to their confidence in the materials and craftsmanship that go into every kit. After subjecting a variety of exhaust brands to ultra-rigorous shaker simulations, heat trials, leak tests, and more, top OEM vehicle makers like GM, Ford, and Toyota choose Borla to supply many of their factory-installed aftermarket exhaust systems — the same engineering that powers your aftermarket upgrade.
