Good morning, Webethree,
It depends on how much of it you have. If you installed a Cat-back system and have the stock system from the cats back, then you should be able to get around $500-$600 for it.
There is someone selling theirs for $565.00 on eBay.
It also depends on what model you have. The ZL1 is said to have the best sounding stock exhaust system.
I would do some research and see what others are selling them for on eBay or Amazon.
Keep in mind that if you sell it on a platform like eBay you will have to ship it and it will be more expensive. Things like headers, x-pipes, mufflers and tips I would sell separately so you make more money since your shipping will be significantly less as opposed to selling and shipping the complete system.
I would also go to the dealer parts department and just get a quote with your VIN for the parts you have at retail. Then reduce it by 30-40% and start there. Dealers usually price their parts 110% over cost.
Hope this helps. Please let me know if I can help further.
