Love my Berk’s. High quality, low cost, crazy sound.

I ordered these cats because my passenger side cat needed to be replaced. An OEM cat was going to cost an eye-watering $1623. I figured that I could save some money and simultaneously get a performance upgrade. I have an Invidia Gemini cat-back exhaust and stock headers. I don't know if any additional power was made, however, my exhaust is a little louder than stock. Installation was about as easy as it could be, build quality is great, and no CEL.

I bought these over a year ago and never installed them, about a month ago one of my o2 sensors gave out. So I decided to install these finally in the process found out my passanger OEM cat gave out. Stock Headers, Berk High Flow Cats paired to my borla exhuat sounds awesome!!!!!! Please note you definitely need the brace I have a 6mt sedan with the JIM WOLF Clutch and Flywheel and for a while I didnt have it. The brace reduces the vibrations you can feel/hear through the cabin.
