Designed to work with BORLA® Cat-Back™ Systems ONLY. This BORLA® SwitchFire® X-Pipe is designed to replace the Merge X-Pipe in BORLA® Cat-Back™ systems 140742, 140743, 140745, and 140746 and the Black Chrome and Carbon Fiber tip versions of them. Contains 2) 2.25" I.D. Inlet x 2.75" I.D. Outlet x 5" Long Adapters, 1) SwitchFire® Assembly, and 4 clamps. SwitchFire® X-Pipe is 25.3" Long x 7.8" Wide x 5" High (dimensions do not include adapters), with 2.75" O.D. Inlets and 3" I.D. Outlets. Pipes are 2" O.D.. Completely eliminating the turbulent center intersection of a standard X-Pipe, BORLA®'S patented SwitchFire® design truly blends the combustion pulses from both sides of the engine for improved performance. The result is an aggressive custom sound and improved power. Each SwitchFire® X-Pipe is 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 numerical control (CNC) manufacturing ensures an accurate fit. Best of all, BORLA® stands behind every SwitchFire® X-Pipe with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.
