It was given to Edwin by the rep from GT-Spec at a Subaru meet months before the release of the actual product. Edwin was going to use it on his black car before he decided to do a twin scroll kit. I bought this from him and had it on my car before you could buy one from GT-Spec. The runners measure about 1 5/8" outer diameter.
