About MBRP: MBRP Exhaust Systems and components are manufactured from high quality steel and is guaranteed to have a perfect fit. The systems are manufactured to withstand even the most extreme road conditions, and to prove it, MBRP backs them with a Lifetime warranty. Featuring lower bend degree angles and smooth mandrel bends, these exhaust systems allow gases to flow easily which in turn reduces gas temperatures. All pipes are mandrel-bent so you can be sure they will keep their shape and size. Pipes which are not mandrel bent may deform over time, leading to decreased airflow and a drop in performance.
