What is a brand new never used BMW Performance exhaust worth?

[PKT RKT]

I have a brand new never used BMW Performance exhaust for an N55 135i.

It’s sitting in its original packaging in the garage, never taken out, in perfect condition.

Thinking about selling my 135i, and haven’t used the exhaust, so wondering what it’s worth if I put it up for sale?

You can still pick these up new for around $700, but they are getting harder to find. As someone in another thread pointed out, at some point BMW changed the part number and now the PE is sold as a silencer without the Y pipe and butt joint brackets. At least that's how mine came when I bought it about 6 months ago. If yours is the latter with the Y pipe, it would a little rarer and more valuable.

I'm in Dallas and willing to talk to you about shipping or hell, maybe even driving my ass up there to pick it up if we can agree on a price.
