No 500S doesn't mean the Shaker.. Thats the name of the mustang. As far as I know his car is basically a 08 GT with an exhaust and intake. I need to look up how much HP he is pullin because he is stock. I'm pullin somewhere around 300HP? Haven't got it tested for an exact number.
Ok I did some research.. and the S in 500S means Serrod. They make costume mustangs. From what I read on their site, all the 500S has performance wise is a Ram air intake and Magnaflow side exhaust. The rest is pretty much cosmetic.. paint, body kit, ect. I couldn't find anything on how much it weighs or the HP so if you guys find something on that let me know. I'm pretty sure, just by looking at the 2, his mustang out weighs mine. The newer bodys look bulky so maybe the weight ratio will help me pull it off. :gringreen:bigthumbsup
