    I am looking at a Cobb up-pipe and I am wondering what makes Inconel so much better over the regular stainless?

    I actually looked up Inconel, but that really isn't telling me how the Inconel is better than the regular SS pipe. I would think that the stainless should be able to handle the heat. Does Inconel have some special heat rejection properties? Are there breakage problems with regular stainless?

    Inconel is stronger at higher temperatures than SS, and better resists corrosion. Inconel has a lower heat transfer coefficient than SS, so it will keep heat in the exhaust better (the real world difference between the two is not noticeable in this application). Stainless will handle the heat if it is thick enough, Inconel is just a better material for the job.

    Not really worth the extra money if you ask me.
