Stainless Steel Cat-Back Exhaust for 1st gen IS300's. $200
Had it on my car for a long time but has never seen snow/salt and barely any rain.
Polishes up nicely as you can see from the pictures - I did not spend the time to polish the entire system. I only took pictures of the polished areas - the rest is on you if you choose to make it shine! Not sure of the brand, got it on ebay long ago. It's designed around the Apex'i N1 system. Sounds very similar also as I have the N1 on my car now.
Shipping won't be cheap - quote it yourself: 53 x 17 x 14 and 40lbs from 44024.
Will meet within a few hours of Cleveland to save on shipping. $200 + shipping

Mazzurri Headers $500
Previous owner (or person before him, who knows) had the stock Y-pipe with cat welded onto the end of the headers. This actually helped me out a lot to pass a visual inspection and to keep the rasp out of the exhaust. If I were to keep this setup, I would find a welder to remove the stock y-pipe portion and put it back to a larger size (2.25" I think?). The important part is that the primaries are still original.
Comes with connecting hardware and gaskets on both ends of the mid-pipe, will not come with header to block gaskets.

I don't have these packaged and boxed up yet to get a shipping cost... but they are heavier than the exhaust so I doubt it would be cheaper than the box size/weight listed above.
Removed them because my Figs headers finally came in :)

Would sell both for $600 (+ shipping)

Let me know if you have any questions or want more pictures. I'm not a thrift store so offers and trades are ignored.

Also have a new Supra TT Big Brake Kit for sale in another post.
