Not sure they'll work Rodger. The LS7 has D port exhaust ports. Looks like Hookers is it.

Stainless vs Ceramic ??
 

Anyone want to explain the long term differences between stainless and ceramic ? I searched the Engine Form and didn't see anything specific beyond a person stating the ceramic rusting after a couple years. I have a choice between the two options for a couple hundred bucks difference ??

Thanks everyone !

My appologies guys, I got lazy and should have done a web search before asking the question here. After a quick google search and reviewing several debate form threads and some tech sites - the ceramic inside/out coating is the best selection for my application.
