The most economical way to increase power off the GTR R35 is to replace the restrictive catalytic convertors to the T1R Turbo Outlet pipes. The Turbo outlet pipes that we developed is made out of SUS316 76.3mm stainless (high heat resistance) with TIG welding process and this will be competable up to 700hp tuned engines. Recommend with T1R O2 Fix (mechanical O2 simulator) so there will be no CEL (Check engine Light).
From our dyno test, we have gained 29whp and 26 ft/lbs torque at 6000rpm and 10whp & 10ft/lbs torque at peak (6400rpm).
