#1...you dont own a cobra
#2....beating on an untuned turbo mustang let alone a non-studded/gasketed one would be similar to going to prison, getting in shower, and purposely dropping the soap. If your not expecting something to go drastically wrong....well then you may need to re-think
Now that im done being an ass sorry that happened and go get yourself some arp's, cometics, and a tune.
