It looks lowered in the first few pictures.

Looks like the cat converter may have been taken out with the custom exhaust along with the resonator. With both those missing, the exhaust is going to be loud.

Is the SES light on still?? If so check to see if the CIG lighter fuse is blown, if it is the OBD 2 port for reading codes will not work.

It also has a wizard air intake system and horrible MSD coil packs. I can't tell if the supercharger pulley has been touched in that picture or if the car has aftermarket headers/powerlog/downpipe.
