GOt a question about the h22a 4-2-1 header. I was wondering if the b section a possible fit for the DC top manifold? I was looking at modifying my DC b pipe to 2.5 since its all mashed up. Came across your headers and amazed at the closeness it has to the DC header. I live in California and which makes it hard for me to settle for HYtech or so forth type headers. I would also love to know if you guys are willing to sell just the b pipe for us Cali-DC sports header owners if not much modification is involved. I'm also looking into your traction bars too.
