Since my factory exhaust manifold cracked I had to replace it with an obx(ebay stuff) stainless tubular header. I had to cut and flange a piece of pipe to make the headers work with my factory tailpipe and muffler. Here are a couple pics of the piece I made, in one you can see the new header. I will get more pics during day light of the header and the cracked factory manifold. I am very pleased with the obx header I got.
