guys with l98 corvettes (85 - 91) would buy exhaust systems off lt1 vettes (92 - 96), but I think they would be less than $100. Don't think you'll get much. cats might be worth somethin as far as scrap
They dont flow to bad, Guys usually like the Titanium ones because they are over half the weight compared to the stainless and they seem to be a bit louder. Also the tips are round on the titanium compared to the oval on the Base coupe exhaust...
