Milltek Primary Cat Decat Downpipes – Nissan GT-R R35 (2009-2015)

Product Code: SSXNI013 | Maximum exhaust flow, ultimate turbo response and pure racing performance for the VR38DETT

The Milltek Primary Cat Decat Downpipes are the ultimate choice for GT-R owners who want to get the most out of their VR38DETT twin-turbo engine.
By completely removing the primary catalytic converters and replacing them with high-quality stainless steel straight pipes of optimal diameter, back pressure is drastically reduced and turbo efficiency is maximized.

This results in immediate and noticeable improvements:

• Much faster turbo spool

• More torque across the entire RPM range

• Higher top-end power

• More aggressive and louder exhaust sound

Made from high-quality stainless steel with perfectly fitting flanges and TIG welds, Milltek offers the quality and durability befitting a supercar like the GT-R.

Key features:

✅ 304 Stainless Steel construction – Durable, heat-resistant and corrosion-free
✅ Decat design – Complete removal of primary catalytic converters for maximum flow
✅ More power & torque – Ideal in combination with ECU tuning
✅ Turbo spool-up – Faster boost, more direct throttle response
✅ Perfect fitment – OEM hangers and flanges, plug & play installation
