Construction & Design

The MBRP Cat Back Exhaust System is crafted from aluminized steel, a durable and cost-effective material that offers solid resistance to rust and corrosion in dry, salt-free environments. This material choice makes it an excellent option for truck owners looking for a long-lasting exhaust upgrade without the premium price of full stainless steel. The system features 3-inch primary tubing paired with 2.5-inch secondary tubing, engineered to optimize exhaust gas flow and improve engine efficiency.

The exhaust tips are formed from high-grade T304 stainless steel, providing a polished, mirror-like finish that resists discoloration and corrosion. The single wall, rolled angle cut design adds a classic, aggressive aesthetic that complements the rugged styling of Dodge Ram trucks.

Performance & Sound

Designed with a Street Profile sound, this MBRP exhaust system strikes the perfect balance between aggressive throttle response and comfortable cruising noise levels. When accelerating, the exhaust emits a deep, throaty growl that enhances the driving experience without becoming intrusive during extended highway drives. This sound profile is ideal for drivers who want noticeable performance audio without the excessive drone often associated with race-oriented exhausts.

The MBRP Cat Back Exhaust System is engineered for direct bolt-on installation using existing factory hangers and mounting points. This ensures a hassle-free upgrade with no need for cutting, welding, or additional modifications. The system fits Dodge Ram 1500 trucks equipped with 4.7L and 5.7L Hemi engines from 2002 to 2010, as well as Ram 1500 models from 2011 to 2018. Proper fitment guarantees optimal performance and sound characteristics tailored to these specific vehicles.
