Borla 60667 BOR Universal Mufflers

(NO 2025 model with 5.7L). This resonator is designed to dampen the sound of select BORLA® Cat-Back™ systems. It is NOT designed to work with competitors or Original Equipment (O.E.) systems. Installation REQUIRES that the small front muffler in the O.E. system is cut out of the system and replaced with the 60667. 3" I.D. inlet and outlet, 18.875" overall length. Built from premium, high-quality T-304 austenitic stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit. Best of all, BORLA® stands behind every direct fit resonator with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.
