has anyone tried wrapping the catpipe and midpipe on top of having a header wrapped? gains?

No, I wouldn't do it. It will eventually rust even if it is stainless steel. You will be trapping a lot of moisture in the tape when it's wet and it will stay moist for a while just eating away at it. Unless there is a reason you have to wrap somewhere, like your header gets to hot and can melt something you shouldn't wrap the header.

stainless steel is called that because it doesnt rust. any moisture that is absorbed by the tape would evaporate because, after all, your exhaust IS hot. about wrapping your header, you do it for more reasons than to prevent certain parts from getting hot. you wrap a header for performance reasons too. by keeping more heat in your exhaust, you can increase exhaust stream velocity, and on turbocharged engines, it can decrease spool time.

Ok, stainless steel can't rust? Tell that to my friend with his mustang. He has stainless steel headers for his car and hasn't driven it in a year and a half. Those headers are rusted. They are not mild steel they are full stainless. It's not even just a top layer, it has to be sent out and coated. So don't sit there and tell me that there is no possibility it can't rust. The Titanic was the unsinkable ship, but it sank. :rolleyes:

yes some, SOME, stainless will rust if it has iron in it which most of the time this is for a specific application that requires it to have different properties than normal stainless but it is also cheaper that said and it being for a mustang which there are alot of different makes for a mustang and price is keep low so using a lower grade of stainless will do that but it will then rust

good stainless will corrode not rust
