The headers might not hurt.
The Cone filter on the TB might be a bad idea, shouldn't there be a MAF sensor on there?
Be sure to look out for some of the retarded low buck to no buck mods the tuners do to ruin these cars.
It appears they did something to damage the fuel economy. The car looks like its at normal hight but make sure the springs have not been torched (heating springs with a torch to lower the car, very bad idea).
I noticed a lot of headers are set up to block flow to the main oxygen sensor, to make the engine run richer for more power.
I have done a mod like this to trick the 2nd oxygen sensor into reading that a catalytic converter was still installed. It normally works.
Blocking flow over and through the oxygen sensor makes it read exhaust as leaner than it really is.
