Product Description

The Borla 140558 Touring™ Cat-Back Exhaust System is a performance exhaust upgrade specifically engineered for the 2015-2020 Chevrolet Suburban 1500 equipped with the 5.3L V8 and automatic transmission. This Cat-Back exhaust replaces the restrictive factory system with a premium T-304 stainless steel design, improving exhaust flow, increasing throttle response, and unlocking potential gains in horsepower and torque while delivering Borla's refined "Sound of Power" Touring tone - louder and more engaging than stock yet comfortable with minimal cabin drone.

Constructed from aerospace-grade stainless steel with mandrel-bent tubing and Borla's patented straight-through, multi-core muffler design, the 140558 system offers long-lasting corrosion resistance and durability. Its dual polished 4" rolled angle-cut tips exit on the right rear, complementing the Suburban's rear profile with a classic performance look. Backed by Borla's Million-Mile Warranty and engineered for a direct, bolt-on installation with included hardware, this Cat-Back exhaust system is ideal for owners seeking a balanced blend of improved performance, refined sound quality, and rugged reliability.
