Invidia [15-21 WRX] [15-21 WRX STI] N1 Titanium Cat Back Exhaust

The Invidia N1 Titanium Cat-Back Exhaust for the 2015-2021 Subaru WRX and WRX STI is a dual-exit full-titanium system that saves weight, improves performance, and sharpens the exhaust note in one package. Fabricated from Grade 5 titanium, the system weighs just under 37 lbs and uses 80mm (3.15-inch) mandrel-bent piping with minimal bends to reduce exhaust turbulence under full throttle, improving throttle response and increasing both horsepower and torque. The non-resonated mid pipe and tuned N1 mufflers produce Invidia's signature aggressive N1 sound, exiting through dual 101mm (4-inch) titanium tips in a burnt blue finish. The exhaust hangers are welded onto OEM-like locations for a direct-fit installation with no extra alterations needed, and new gaskets, hardware, and a pair of removable silencers are included. Note: with a stock J-pipe or downpipe, the GrimmSpeed Subaru stock-DP-to-aftermarket-cat-back adapter (p/n 077046) is required.
