MBRP S5021AL 3 Inch Cat-Back Exhaust System Aluminized Steel Dual Split Rear Exit

The MBRP S5021AL Cat-Back Exhaust System is engineered specifically for 2019-newer Chevrolet Silverado and GMC Sierra 1500 trucks equipped with the 2.7L engine. This Armor Lite series system delivers enhanced performance, improved exhaust flow, and a signature MBRP sound at an exceptional value.

Performance Enhancement:

This exhaust system features 3-inch mandrel-bent tubing that transitions to 2.5-inch dual split rear exit pipes, providing up to 69% increase in exhaust flow compared to the restrictive factory system. Mandrel bending eliminates ripples and kinks in the tubing bends, ensuring smooth, unrestricted exhaust gas flow. The result is improved engine breathing, increased horsepower and torque, better throttle response, and enhanced fuel efficiency.

Premium Construction:

Constructed from heavy-gauge aluminized steel with fully sealed seams, this system offers excellent durability and rust resistance for mild to dry climates. The robust tubing resists dings and dents from road debris while maintaining the same fitment standards as MBRP's premium Armor Pro line. The system utilizes factory hanger locations for a direct bolt-on installation.

Refined Sound Quality:

MBRP incorporates Helmholtz resonator technology into this cat-back system to deliver a full-bodied, moderate exhaust tone with enhanced sound without annoying cabin drone. The system includes two 4.5-inch OD polished stainless steel exhaust tips that provide an aggressive appearance and distinctive MBRP exhaust note.
