The Japspeed Stainless Steel Silenced Decat Pipe is designed to improve exhaust flow and engine performance on a range of Nissan 180SX, 200SX, Silvia, Skyline and Pulsar GTi-R models.
Replacing the restrictive factory catalytic converter with a free-flowing stainless steel decat pipe allows exhaust gases to pass through the exhaust system more efficiently, helping reduce back pressure and support increased engine power output.
Manufactured from high-quality T304 stainless steel, this decat pipe features a 3-inch bore to improve exhaust gas flow compared with the original catalytic converter.
Unlike conventional straight-through decat pipes, this version incorporates a built-in silencer designed to reduce exhaust noise by up to 15dB. This makes it particularly suitable for track and drift applications where noise limits may apply.
The pipe features TIG-welded construction and CNC-machined flanges for strength and durability. An integrated sensor boss allows fitment of the original exhaust temperature sensor.
Designed as a direct replacement for the standard catalytic converter section on compatible vehicles.

Not suitable for Nissan Skyline R34 GTT models.
Gaskets and bolts are not included.
Sold for off-road and track use only. This decat pipe removes the factory catalytic converter and will not pass an MOT emissions test where a catalytic converter is required.
The built-in silencer is designed to reduce exhaust noise by up to 15dB, although actual noise reduction will vary depending on the vehicle and exhaust configuration.
