Installation REQUIRES cutting the Original Equipment system. The Loop Delete Pipe provides more space underneath your Wrangler JL/ JLU or Gladiator JT. Built from 2" diameter 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 Loop Delete Pipe with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.
