Boost Logic 4″ Titanium exhaust with flaps Upgrade Nissan GT-R R35

Boost Logic R35 4″ Titanium Exhaust Valved Section Upgrade

**This is for the muffler section of the exhaust only, you will need to reuse your existing tips**

Our boost-activated valves stay closed under 7psi of boost, keeping your GTR smooth when cruising and idling. Once you exceed 7psi of boost, the valves will open to create the greatest possible airflow, allowing your engine to produce the greatest possible power. We designed this upgrade to prevent excessive back pressure or power loss when the valves are closed. When the valves are open, this system flows as much as our standard race-proven titanium exhaust system.
