These pipes are intended to add the NPP (dual mode option) valves to Borla® systems 11920 and 11921 that did not come with NPP valves. They can only be used with mufflers that have dual tips exiting the mufflers. These pipes replace the outside tail pipe on each muffler. Outside tail pipe on 11920 or 11921 must be cut off of the Axle-Back assembly in order for these tail pipes to be installed. Clamps included. Wiring and actuators are not included. They are not intended to add NPP to a vehicle that was not originally equipped with NPP.
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-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.
