Here, you are looking at the HKS Hi-Power Catback Exhaust for the 2015-2021 WRX/STI. 

HKS has taken their time to design a free-flowing exhaust that sounds great. Low exhaust resonance is eliminated with sound tuning from the built-in resonance pipe.
They aimed to produce an exhaust system to allow owners to enjoy that great boxer sound and succeeded.

Details:

  • 304 Stainless Construction 
  • Twin-tube resonator 
  • 97mm burnt tips
  • 74.7mm to 60.5mm piping diameter
  • Direct bolt-on to OEM downpipe
  • Gaskets and hardware included
  • 90dB sound output makes for a street friendly setup 

Note: A OEM Downpipe to 3in Cat Back Adapter may be necessary if the diameter of the new cat-back exhaust systems piping is different from the stock system, or if there are compatibility issues between the new components and the existing downpipe.
