Invidia Stainless Tip Single N1 Street Catback Exhaust – 2011-2014 Subaru WRX STi Sedan

Application: 2011-2014 Subaru Impreza WRX STi Sedan
Piping Diameter: 76mm
Tip Diameter: 101mm

Invidia's full 76mm (3 inch) mandrel bent stainless steel piping optimizes flow and minimizes turbulence with a unique exhaust path that deletes all unnecessary bends, releasing horsepower that would normally be restricted. So whether you choose the "Racing" or the "Street" N1, you will be getting an exhaust system that was designed to provide your 2.5L with more power. This system features a Single Stainless Steel Tipped muffler.

Where the two Invidia N1 styles differ is their midpipe. The "Street" midpipe features a flex joint for easy installation as well as an inline resonator to keep this system sounding more aggressive than the overly subtle stock system while maintaining daily driveability. The even more aggressive Invidia N1 "Racing" exhaust features the same 76mm (3 inch) mandrel bent stainless steel piping but does not have a resonator or flex section. The result is a louder, racier exhaust tone than the ‘Regular' N1.
