Invidia N1 Street Cat-Back Exhaust Titanium Tips | 2008–2014 WRX / 2011–2014 STI Sedan | HS08SW4GTT

The Invidia HS08SW4GTT N1 Street cat-back exhaust delivers real power gains on the 2008–2014 Subaru WRX and 2011–2014 STI Sedan with a deep, aggressive-yet-refined exhaust tone suited for daily driving. Full 76mm (3") mandrel-bent stainless steel piping optimizes flow and eliminates unnecessary bends to free up restricted horsepower.

N1 Street vs. N1 Race

Both share the same 3" mandrel-bent stainless piping. The Street midpipe includes a flex joint for easy installation and an inline resonator for a deep, touring-style tone. The Race midpipe has no resonator or flex section — louder and more aggressive at wide open throttle.
