So I thought I purchased a dual exhaust but I really purchased a single. I was looking for quieter but what I got was lighter. I'm gonna take a loss on this. I have a new, in box q300 exhaust for a 2008 + WRX sedan. From what I can read, the single exhaust flows as well as a dual (or better), weighs 30 lbs less, but is a bit louder. I was looking for quiet. So, it will sit in my garage until it sells. I'm taking a loss on it at my listing price but this is what it will cost me to send it back as a return as well. I'd might as well give someone a good discount.
