For those who have purchased our Axle-Back system or GM Performance rear mufflers and are looking to upgrade with a 2.5" diameter Merge X-Pipe with Mid-Pipes, here you go. X-Pipes unleash horsepower and create a custom sound. This is essentially the front portion of our Cat-Back(tm) system for the 2010-2015 Camaro 6.2L. Works with Borla(r) 11774, 11775. 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(r) stands behind every X-Pipe with Mid-Pipes with a Million-Mile Warranty. Just what you'd expect from the worlds most experienced (and most winning) exhaust brand.
