NOT recommended for use on convertibles. This Resonator is designed to replace the Merge X-Pipe in select BORLA® Cat-Back systems to dampen the sound. Use ONLY with BORLA® systems. It is NOT designed to work with competitors or Original Equipment (O.E.) systems. The resonator contains an internal H-Pipe for increased performance and improved sound. It has dual 2.25"diameter inlets and dual 3" outlets. The resonator fits Vehicles With or Without Active Valve Exhaust. Built from premium T-304 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.
