The Japspeed Stainless Steel Decat Pipes are designed to improve exhaust flow and engine performance on Nissan GT-R R35 models from 2007 to 2016.
Replacing the restrictive factory catalytic converters with a pair of larger bore, free-flowing decat pipes allows exhaust gases to exit the twin turbocharged V6 engine more efficiently, helping reduce back pressure and improve engine response.
Manufactured from high-quality T304 stainless steel, these decat pipes feature a 3-inch diameter and are designed to support increased power output by reducing restrictions within the factory exhaust system.
The pipes incorporate cast ends for additional strength and durability in areas exposed to high temperatures and mechanical stress. This combines the corrosion resistance of stainless steel with the robust construction required for high-performance turbocharged applications.
Featuring TIG-welded construction and CNC-machined flanges, the decat pipes are designed for direct bolt-on fitment, providing a straightforward upgrade to the original catalytic converter sections.
For maximum performance gains, an ECU remap is recommended after installation to take full advantage of the improved exhaust flow.
