I have the stock exhaust from my 2010 Tacoma DC SB which was removed and replaced with the TRD exhaust when it was 3 months old back in March of 2010. It's practically new and has been in storage in my basement for over 3 years. I believe it will fit 2005-12 Tacomas with the Access Cab or Double Cab with the short (regular) bed.
I live in the southern NH area so ideally it would be a local pickup. PM me if you're interested.
