Every Borla spec sheet lists the same line: T-304 stainless steel. It's easy to read past it as boilerplate. It isn't. The specific grade of stainless steel a system is built from determines how it survives thousands of heat cycles and years of vibration, long before sound level or pipe diameter enter the picture. Here's what "T-304" actually means, and why it's the grade Borla builds every system from.

Chevrolet has confirmed a fundamental architecture change to the Silverado 1500, and it's not the styling. Arriving late 2026, the next-generation Silverado retires the 5.3L and 6.2L Gen V small-blocks that have anchored Borla's Silverado lineup since 2019, replacing them with two ground-up V8s: a 5.7L and a 6.6L. If you're tracking what an exhaust upgrade looks like for a 2027 truck, here's the confirmed spec sheet so far, and the engineering question it raises for everything downstream of the manifold. For fitment on the current 2019-2026 generation, see the Silverado 1500 Buying Guide.

When Christopher Polvoorde straps into the cab of his Mason Motorsports All-Wheel Drive Trophy Truck, he needs to think. Race pace, terrain changes, team communications over the radio: the last thing a professional driver needs is relentless exhaust drone eating away at his concentration mile after mile.

But when that truck clears a jump or comes screaming through spectator zones, it needs to sound exactly like what it is: a high-output racing machine built without compromise.

The C8 Corvette lineup- Stingray, Z06, E-Ray, and ZR1- each pairs with a Cat-Back system engineered around that specific platform's engine and factory valve hardware. Picking the right C8 Corvette exhaust comes down to three things: which C8 you have, which sound level you want, and whether your car has the factory NPP hardware Borla's system is built around. Every system is T-304 stainless steel and backed by the Million Mile Warranty. Here's how the pieces fit together. For full part numbers and fitment by generation, see the Corvette Exhaust Buying Guide.

Borla Performance Exhausts has released Cat-Back and Axle-Back exhaust systems for the 2024-2026 Ford Mustang EcoBoost. Both systems are 50-state street legal and tuned specifically for the 2.3L EcoBoost engine. The Cat-Back is a direct bolt-on. The Axle-Back requires cutting the stock exhaust to clamp on.

Borla Performance Exhausts has launched Cat-Back exhaust systems for the 2024-2026 Ford Mustang Dark Horse. These bolt-on, 50-state legal systems are built from T-304 stainless steel, available in S-Type and ATAK sound levels, and compatible with the factory Active Exhaust system.

Borla Performance Exhausts has released Cat-Back and Axle-Back exhaust systems for the 2024-2026 Ford Mustang GT. Built from T-304 stainless steel and backed by Borla's Million Mile Warranty, these systems are bolt-on compatible and 50-state street legal.

What does a vintage Rolls-Royce have in common with a modern Ford Raptor or a high-performance EV? They are all part of the 50-year journey of Borla Performance Industries. At Borla, we don't just build exhaust systems; we engineer the emotional connection between a driver and their vehicle.

During the 2025 SEMA Show, our President, David Borla, sat down with Mike Caudill on the Chasing Horsepower stage to discuss our "top of the food chain" status, our heritage in material science, and how we are defining the future of automotive sound.

An engine’s signature sound is rooted in frequency and physics, not opinion. Before tone or volume, there is firing frequency. That baseline rhythm is the audible result of pressure pulses leaving the cylinders and interacting with both the exhaust system and the vehicle’s cabin.

BORLA® Performance Industries, the global leader in high-performance stainless steel exhaust technology, is proud to announce the release of its new S-Type Cat-Back™ exhaust systems for the 2022-2025 Volkswagen Jetta GLI.
