GRiP Series Cat-Back Exhaust System by ARK Performance

The ARK GRiP exhaust system provides the serious enthusiast a combination of sound,style, and quality craftmanship. As a leader and innovator in aftermath exhaust systems ARK is highly recognized for their exclusive designs, proven performance gains, and the sigificant ARK exhaust note that is resonant, pure and deep.

ARK concentrates on the best materials so that you can enjoy the quality behind every ARK Performance exhaust system. All of their systems are handcrafted from T304 Stainless Steel. Each exhaust has thicker-than-competition sidewalls leading to a stronger construction without adding a significant amount of weight. All of the bends in their systems are mandrel bent to maintain the tensile strenth and mechanical properties providing a smooth and even exhaust flow. In addition their signature x-pipe developed in house provides a true and even flow that no competitor can match.

Each exhaust system is engineered to sound like a symphony, at least to gear heads. ARK Performance mufflers have unique and signature cores redefining exhaust sound engineering. With their Helmholtz technology they are able to reduce in-cabin drone without sacrificing performance.

The original tip finishes that each ARK Performance exhaust system comes with provides the finishing touch to a beautiful stainless steel work of art. They are available in burnt or polished.

Quiets down after only a short time

After install I debated removing it. The drone inside and overall loudness was too much imo. I only enjoyed it when hard on throttle , maybe like 20% of the time. After less than 500 miles, it is without a doubt much quieter and I plan to leave it on. Good quality, happy with purchase.
