Default Ceramic coating Exhaust components

Is there going to be any gain other than noise reduction?
Reason I ask is I am having my Magnaflow muffler and 3" HF cat ceramic coated.
Also, should I leave the cat bare for any reason?
I mainly am after noise reduction with this (hence I bought the Magnaflow to replace the IMCO HF F-body muffler), but any power gains (no doubt minute if any) are very welcome.

I read an article. I think it was posted at ZZP regarding exhaust manifolds and the differences in ceramic coating, wrapping and leaving stock. Very good info.. bascially ceramic was the way to run.

While I can't say I actually read Marty'* post overly well...

I can't see any noise reduction properties from ceramic coating. ...or paint.

X2... How can ceramic paint have any affect on sound? Unless you had a leak that it was sealing, I can't see it.

I am looking to avoid the drone associated with aftermarket mufflers at while cruising at hwy speeds. I mainly want the majority of the sound to come out of the exhaust tips and stay back there.

But now the sad part... I got a call from the shop saying they couldn't coat the cat or the muffler because they are stainless steel and the ceramic would rattle, break up and fall off after a very short time.... if it was aluminum it would be a different story. :( :( :(
So now I have to go get some high temp paint, but I'm not sure what color I want.
Maybe I will just have to dynamat above the muffler, both inside and outside the trunk and under the back seat. :( That'* not the way to go about reducing weight.

It wouldn't have done anything acoustically anyway.
