Weapon R 08-10 Nissan Skyline GTR R35 3in O2 Housings

If you're looking to get more out of your 2009-2010 Nissan GT-R's exhaust system, these 3-inch O2 housings from Weapon R are a solid option. They replace the factory O2 sensor housings with a larger, smoother-flowing design, which can help your engine breathe a little easier. This often translates to a slightly improved throttle response and a deeper exhaust note.

These housings are constructed from stainless steel, which is a good choice for exhaust components because it holds up well against heat and corrosion. The 3-inch diameter is designed to match larger aftermarket exhaust systems, ensuring there's no bottleneck where the O2 sensor housing meets the rest of your exhaust. Installation typically involves removing the factory housings and bolting these in their place, though you'll want to refer to the manufacturer's instructions for specific details and any necessary hardware. Keep in mind that these are not CARB approved and cannot be shipped to California.
