Construction & Design

This exhaust system is crafted from aluminized steel, a material known for its excellent resistance to rust and corrosion in dry environments. The aluminized coating protects the mild steel core, extending the life of the exhaust system without the premium cost of full stainless steel. The polished tips are made from T304 stainless steel, providing a mirror-like finish that resists discoloration and corrosion while adding a classic, aggressive look to the vehicle’s rear.

MBRP’s engineering ensures precise fitment and optimal exhaust flow, with smooth mandrel bends that reduce turbulence and backpressure. The 3-inch tubing diameter is carefully selected to balance performance gains with sound quality, delivering a deep, throaty exhaust note that enhances the SRT’s naturally aggressive engine character.
