Fantastic exhaust
I had the Q300 dual exhaust on my 2017 sti but I crashed that car. When I got my 2021 sti I knew I wanted another Q300. This time I decided on the single exit version to try something different. This exhaust looks more stealth, actually looks like the OEM exhaust from an 2004 sti. I received the exhaust 3 days after I placed my order so I was really happy. This single exit Q300 actually sounds better than the dual exit version. It's slightly louder with a much deeper rumble, honestly This is the best exhaust I've ever heard on an sti. I would highly recommend this over any exhaust on the market.
