SUPER OUTLET PRO II
Mine's have designed and developed the Super Outlet Pro II for R35 GT-R to reduce the exhaust pressure and obtain a better exhaust efficiency whilst changing the first catalyzer which has strong resistance to the exhaust system into the straight pipe to be used in a closed circuit. Plus it will make the car lighter by removing the catalyzer.
We used stainless steel because of the exposure to high temperature in the first catalyzer. For installation, the special service tool or SST (Nissan genuine part number: KV101-13700 or a socket specifically for the removal of O2 sensor) is required.
