Order straight from TTI. I really don't think anyone else has them. I ordered some TTI exhaust for my slant six from Mancini. Took over two months to get it, because they didn't have it in stock like they told me and they dragged their feet on the order. It was dropped shipped from TTI. On the second and third pieces, I ordered straight from TTI, got it much quicker and even saved a few bucks.
