2001 corvette, some modifications. Does this take away or add to the car

I sold my 96 a few weeks ago and have been looking for a 99 - 01 car.
I found a blue one. Love the color. Not sure about modifications.
Car has the following. Would these kill re-sale or would they have no
affect.

* Hurst Short Throw Shifter
* Vara-Ram Ram Air
* TPIS Long Tube Headers
* Corsa Touring Exhaust
* 3.90 Rear End With Hardened Shaft
* 18
* Dyno Tuned At JD Auto
* Engine Has Approximately 410 Horsepower
I don;t need the stuff. It is already on the car.

You know, my car was a bitch getting in and out. BUT the seats were
definitely better then the 05 seats. My $0.02 anyway.
