Im looking at buying the side exhaust kit with the side skirts for my stang. on summitracing.com they have a borla kit for 950 dollars and a ford racing setup for 650 dollars. both of them have borla equipment. obviously 300 dollars difference is alot. can anyone tell me the difference between them. i like the borla kit with the SVO imprint in the side skirt. i cant tell from the picture if the ford racing one says SVO or not? does anyone know. also, hows the sound?
