This has probably been discussed many times over, but I can't seem to find an answer in the archives to the following... For a NA 6 port, 13b, why choose 321 stainless steel over 304 for the exhaust? Or Inconel 625 over 321? Is it a comfort level or a need? Also, it seemed that 321 .035 was living on the edge and that most were using in the .060+ range. Is this the prevailing wisdom? Finally, is visually possible to determine what is 304 and what is 321? I ask this as I am going over to a used parts race shop and they just have a pile of exhaust pipe, no rhyme or reason to the pile. Thus, if it really didn't matter on the SS alloy I could just pick the pipes I needed and hack and slash as necessary. Thanx!!! Many thanks to all who posted pics of their coils and water pump surgeries!!!! -Scott __________________________________ Do you Yahoo!? Win a $20,000 Career Makeover at Yahoo!
