Construction & Design

The MBRP Cat Back Exhaust System is crafted from T409 stainless steel, a value-focused alloy that offers the same aesthetic appeal as T304 stainless steel but with slightly reduced durability, making it ideal for moderate climates with occasional rain exposure. This material choice balances cost and longevity, backed by a lifetime warranty for peace of mind.

The exhaust tip features a dual wall, angle-cut design made from premium T304 stainless steel, polished to a mirror finish. This construction not only provides a striking visual upgrade but also helps dissipate heat effectively, protecting surrounding body panels from heat damage. The 2.5-inch tubing diameter is engineered to optimize exhaust flow without sacrificing low-end torque or drivability.

The MBRP Cat Back Exhaust System is tuned with a Street Profile sound, offering a perfect blend of aggressive tone under throttle and a subdued character during cruising.
