348 Tubi & Stebro

I took everyone's advice and am currently in the process of converting my 348 back to stock. I ended up trading my Speelines to LIEBKID who also purchased my F355 taillight conversion.

Anyway, while my car is in the shop I was toying with the idea of pulling off the Tubi exhaust and Stebro euro resonators and putting the stock exhaust and cats back on.

I know the Tubi wont detract from my car's value, but would I get any more for the car with it in place? If not, wouldn't I be better off to simply sell the items separate? I paid $2,700/$550 respectively, so my question is what are Tubi and Stebro going for in the used market?

Thanks,
Chris
