Invidia Q300 Cat-Back Exhaust Titanium Tips | 2008–2014 STI / 2011–2014 WRX Hatchback | HS08STIG3T

The Invidia HS08STIG3T Q300 cat-back exhaust delivers the performance of the N1 series with a significantly quieter, deeper exhaust tone — making it the ideal choice for drivers who want real power gains without the aggressive volume. Dyno-proven to add 17 WHP and 5 ft-lbs of torque on the 2008–2010 STI, the Q300 uses specially sized resonators and muffler baffles to maintain output while producing a refined, touring-style exhaust note.

• Titanium tips
