My B pipe is done. I need a replacement. I know the stock part number (18220-ST7-J01). Thing is there are hard to come by. Don't need new, or racing, or fancy. Just a B Pipe thats not busted in half. I have heard there are options as far as swapping them with other models of Integra, like the DB8. Also the Civic Sedan of the same. year. Please help if you know ...
