Amazing Product

By: on 13 January 2020
Before I begin the review, let me tell you a bit about myself. I am 20 years old, I own a 2015 BRZ with no other mods done yet and have owned this exhaust for 4 months. I have always had quiet cars, which make zero sound. So my ears would be quite sensitive to loud exhausts but not as sensative as older people. I was stuck between Q300 and the R400. Hopefully this review helps you decide. This exhaust sounds absolutely amazing. No doubt about it, you can obviously hear it on YouTube. In terms of how loud it is... it's definitely noticeable inside the car, not obnoxious what so ever but rather pleasing to the ear. You can easily have a conversation in the car and the exhaust will be blocked out by playing music. I personally had this exhaust fit by a mechanic, they had the tools and the lift which allowed the installation to be done in about 10-15 min. However, one problem with this exhaust (and many I have seen on YouTube) have fitment issue, where one side will lean more to one side than the other (which is why I rated the product 4). My mechanic just pulled very hard on the hanger and it fixed the issue but this will obviously be difficult on the ground (if you decide to install it yourself). Hopefully this helped you decide between Q300 and the R400 :)
