Super loud exhaust

By: Kavin
Sounds great on my sti 2015. It gives the legendary subie rumble. This is the best exhaust on the market. Way more better than the invidia R400. Couldn’t be happier

Awesome exhaust!

By: Sam
Quick delivery considering it came all the way from Perth for starters. This exhaust is amazing, its not too loud and it definitely isnt obnoxious. Just a classic boxer rumble with respectable grunt

Description very true!

By: Alexander
Definately a deep sounding system that suits the vehicle. Did some dB tests & at 1m through varying RPM ranges got to 83 dB & higher up rev range the lower the dB. Yes, some drone in cabin at

awesome sound
