I have a used unequal length Borla header for sale. Lets say $450 shipped and $400 local pickup. I never got a chance to install it but the previous owner said he had no problems with it. it had spark plug arrestors in the O2 sensor bung already.
I have not been driving the car much at all since I have gotten my company vehicle so between that and my WRX swapped porsche and my LQ9 swapped silverado, the car that isn't paid off must go. I also have a K&N panel filter that I did install as well as a 2014 BRZ Limited with 11,500 miles for sale.
My travels occasionally take me as far west as Victoria and San Antonio, so wee may be able to work something out in that area.
