The Borla Touring Cat-Back system for 2019–2025 Chevrolet Silverado and GMC Sierra (4.3L/5.3L) uses a 3" main diameter and a side exit to deliver a mellow Touring sound level with no drone inside the vehicle. Constructed from premium T‑304 stainless steel with precision CNC manufacturing and mandrel bends, it improves exhaust flow and driving feel. The system finishes with a 4" bright chrome tip and is intended for factory side-exit vehicles; an adapter may be needed for certain wheelbases.
