Borla designs their exhaust products to ease the stranglehold your stock exhaust system has on your vehicle's engine. Borla's patented technology opens the way for escaping gases, and maximum exhaust flow equals improved performance. This translates into more power and torque when you plant your foot, along with increased fuel economy at cruising speeds. Borla builds its exhaust systems from aircraft-grade T-304 stainless steel, so they're lighter, stronger, and last far longer than factory exhausts - all with easy bolt-on installation. Extensive research determines which tube size will get the most performance from your car. Smooth mandrel bends and efficient design give the exhaust a mellow rumble while keeping most of the sound behind the exhaust tips. This means you won't get unwanted droning noises in the cockpit while cruising. Every Borla exhaust system gives you precision fit with motorsport-inspired styling. BORLA Cat-Back? exhausts feature patented, straight-through and multi-core technology to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy and the distinctive BORLA Sound of Power respected by motoring enthusiasts everywhere. Each system is built from premium austenitic stainless steel, to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow and power, and precision computer-controlled CNC manufacturing ensures an accurate fit. Best of all, BORLA stands behind every system with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.
