Tailored specifically for 2015-17 models, this system utilises top-grade T-304 stainless steel for exceptional durability and resistance to corrosion. The precision mandrel bends ensure an unobstructed exhaust flow by maintaining a uniform tube diameter, minimising backpressure for better engine efficiency.
