Are the stock parts worth anything
 

So on Saturday I installed a 350hp performance pack from SLP, a Roush suspension setup, and a Hurst short throw on my friends 2006 GT.

LT headers, x-pipe, axle back, CAI, springs, struts, and sway bars.
I installed everything but the underdrive pullies. I'm not a fan of them, since they don't charge the battery at idle.

My question is I've got all these stock parts with 10,000 miles on them. Are they worth anything or is it off to the junkyard? Thanks.

Also if anyone has questions about these installs feel free. I've got a buncha pics of the installs too.

You can probably get some money on ebay.

If I did it again, Id keep all my stock parts. You never know whats going to happen in the future.
