This guys add on ebay when he first put it up for sale said it was off of a 98 NSX& it was rare & valuable with a buy it now at $2250,I emailed him and told him the muffler was neither rare nor valuable and we took them off of our cars and threw them away when we put on an after mkt.exhaust, also told him it wouldnt fit a 98 as it was an early model and would only fit up to a 96,he emailed back and said gee thanks for the info,not that I care.
