The most economical way to increase power off the GTR R35 is to replace the restrictive catalytic convertors to the Turbo Outlet pipes. Produced from SUS304 stainless. These pipes weigh approx only 3.4 kg, stock being 10.3 kg. Plus the benefit of increased power!
These pipes will allow the VR38 BEAST out of its cage as they remove the power robbing pre-cats and provide your turbo’s with some room to breathe. The result of removing these highly restrictive catalytic converters is a deep growl, improved turbo spool, and an overall improvement in the responsiveness in the car throughout the power band.
Note when you remove the oem engine cats check engine light will appear on EDM & UDM not JDM. We can remove this with the accesstuner software, so you’ll need an accessPORT. You will need one anyway as your 35 will run lean.
As catalytic converters will be removed, it is only for offroad use.
