I plan to go with either the Tomei ELH or the Killer B Holy Header. I realize these two options are at opposite ends of the cost spectrum. However, the tuner I am working with recommended the Tomei due to the affordability and continued success they have had with them. However, they had nothing bad to say about the Killer B setup, but specified that a daily driven STI, only seeing occasional track use, should not have issues with a 304 SS header cracking.
This leads to my question, how important is it wrap the headers? This seems to be a large contributor to the 304 SS headers cracking. Is the added benefit worth the additional stress on the exhaust manifold?
