Perfweld headers.com http://www.perfweldheaders.com/svsm.html- "Stainless Steel Headers can be repaired, or modified at any time in their lifespan due to the simple fact that they do not rust and do not need a Thermal coating. Mild Steel Headers are very tough to repair or modify due to Thermal Coatings and rust"
If sd are stainless steel, why are they rusting?
also, ssautochromes Pontiac Performance Racing Products for International Sales from SSAutochrome Inc. site states that they are "mild steel"
Also, 1 3/4's is inside diameter? I was told by someone on the site they were 1 5/8's.
You will not be able to just throw SD's on, It is a minimum cost of $300 and therefore much closer to 200% more, but idk why the percentage matters.
304 is the MAIN reason the price is higher, if your fine with speed daddys then good for you. The 304 plus benefits listed earlier on my comparison is why I like the wbs headers.
Not to mention, that ubend is not a pretty sight if you look underneath the car..
an inch? lol, i would not beat my car like that.
