Mustang EcoBoost 2015-2020 Resonator

Use this muffler with Cat-Back™ system 140584 for "Touring" sound level, and with 140585 for S-Type sound level. This is not a stand alone muffler and was not intended to fit with factory pipes. Built from premium T-304 stainless steel, superior to T-400 series (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer-controlled CNC manufacturing ensures an accurate fit.

Best of all, BORLA® stands behind every connection pipe with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.
