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!

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
