The Japspeed Adjustable Stainless Steel Decat Pipe is designed to improve exhaust flow and engine performance on Nissan 200SX S14A, S15, Skyline R34 GTT and Mitsubishi Lancer Evolution 4, 5 and 6 models.
Replacing the restrictive factory catalytic converter with a free-flowing decat pipe allows exhaust gases to pass through the exhaust system more efficiently, helping reduce back pressure and improve throttle response.
Manufactured from high-quality T304 stainless steel, the decat pipe features a 3-inch bore to reduce exhaust restrictions and support improved engine power output, particularly on turbocharged applications.
The adjustable-length design allows the pipe to accommodate different vehicle applications, making it a versatile replacement for the original catalytic converter.
Featuring TIG-welded construction and CNC-machined flanges for strength, durability and secure fitment, the decat pipe is supplied with gaskets and bolts for installation.
