This Polar Diesel exhaust roars with T409 stainless steel strength, delivering smoother flow and hotter performance. Its single‑side exit and pre‑bent hangers make installation a breeze, even on rugged off‑road rigs. Expect lower EGTs, better fuel mileage, and a noticeable boost in horsepower and torque. Remember, it’s built for off‑road fun, not street‑legal cruising.
