Can someone explain the difference in performance between the three different models?

NHS4201s
NHS4201b
NHC4201

Why would anyone spend the extra money for the NHS4201s? Is there any performance difference between the cheapest and the most expensive?

 

The stainless ones will last longer but release more heat into your engine bay.
The ceramic ones keep the heat in better but are more likely to crack or rust if you scratch them.
No performance difference...

 

There is a 3rd version though. I'm aware of the stainless and ceramic.

However, why is there one listed for $1,200? What does that one do that the other don't?

 

The other is brushed. It just looks custom and does not give any better performance. The stainless is the most expensive, then brushed, then ceramic. I would get the ceramic but Stillen says it will lower the boost on my S/C and I will probably loose power.

 

NHS4201s = polished stainless steel

NHS4201b = Brushed stainless steel

I dont know why the polished set is 200-300 bucks more.

 

NHS4201s - stainless steel, polished(shiney) finish
NHS4201b - stainless steel, brushed finish
NHC4201 - mild steel with ceramic coating

 

Heres a pic of brushed:

Thanks guys for clearing it up!
