I'm listing this for my brother, he picked it up during the summer and never got around to using it. It is used, but in good condition there is a dent in the resonator but it does not affect sound and it doesn't leak at all. I own one myself and it is AWESOME. The QUIETEST exhaust you can buy for a 240sx. It retails at $577. The price is $350. It's in Orlando, so I'll to pick it up the next time I go home. The dent is about the size of my thumb right at the top of the resonator in the mid pipe, nothing crazy. It looks a little dirty in this pic, but the tip has been cleaned and is shiny again. It's for an s14.
