S2 - 590bhp

Our S2 upgrade features the Y-pipe and the rest of Milltek's performance exhaust system which replaces the restrictive standard rear silencer.


The S2 level of tune features the Y pipe from the S1 conversation but is mated to a a full exhaust system that replaces the OEM exhaust, that proves quite restrictive when we are in persuit of power.  Engine performance is also improve as we improve its ability to breath more efficiently.  We do this by replacing the OEM air filter with a freer flowing items that fits directly into the standard factory air box.

These new components are combined with an ECM remap using the ECUTek Advanced ECU Technology giving you one of the most popular upgrades for the GT-R.

Regardless of what you will read on the internet or be told by many independents garages modifications cannot be hidden.  Any attempt to hide/erase the modification or tamper with the VSDR system will likely result in repairs not being covered by Nissan Warranty.
