Common sense prevails tho....
•Can see its been used due to the colour
•Mileage won't make a blind bit of difference
•anyone looking at this item will already be past the level of tuning that requires aftermarket elbow
• cracks would show up on any pics that potential buyers would request, just as the seller has offered
Iirc, selling rules require description of item, picture and price. All of which were included in OP
