How hard is it to install and how much power do u think ill gain from it with the standard kit (6PSI). Also does any one have any pics of one installed with either the satin or polished finish. Im already putting 275rwhp and 315rwtq to the wheels. I was thinking i would gain about 80-85hp and 100 or so torque. Any information is appreciated. I have a 1995 cobra.
