Invidia N1 Single Outlet Cat-Back Exhaust 2015-2021 WRX/STI

N1 offers an aggressive look and sound at a reasonable price point. This single-outlet variant boasts minimal weight — removing the Y-pipe and one of the mufflers reduces the system to bare minimum to get the exhaust to the back of the car.

Every Invidia exhaust is constructed with high-quality 304 stainless steel, CNC-machined flanges, and manufactured with a polished finish. Each system features mandrel-bent stainless steel piping for maximum exhaust flow and reduced back pressure. These exhausts are engineered to produce strong mid to top-end power gains, as well as an increase in horsepower and torque.

3″ piping throughout, with a single 4″ tip.  Choose between burnt titanium or polished stainless steel slash-cut exhaust tip. For the ti-tip exhausts, you can also choose resonated (slightly less loud), or non-resonated (loud!).

Fits all 2015-2021 Subaru WRX and WRX STI.
