Show original supplier description
Constructed from premium T304 stainless steel, this system is resistant to rust and corrosion, making it an excellent choice for challenging climates and off-road applications. It features a lifetime warranty, underscoring its robust build quality. This cat-back system boasts a 3-inch tubing diameter and a dual rear exit configuration, complemented by 4.5-inch diameter, dual-wall, angle-cut tips with a mirror-polished finish. The Armor Pro is designed with a 'Street Profile,' offering an aggressive exhaust note when you accelerate but remaining unobtrusive during highway cruising, striking a balance between performance sound and daily drivability. All tubing is mandrel-bent to ensure smooth exhaust flow and prevent restrictive kinks, which contributes to enhanced engine breathing and improved performance. It is specifically engineered for the 2016-2024 Infiniti Q50 models equipped with the 3.0L V6 engine, compatible with both RWD and AWD configurations. The system aims to reduce back pressure, leading to increased horsepower and torque, while also providing a distinct, aggressive exhaust note.
