Header cut out options?

I've got a set of Sanderson headers with solid aluminum plates on the cut out, and I was wondering if anyone made a louvered cut out cover that would let some noise through, but not all of it.

Or, maybe a baffle would work inside the header? Where would I find something like that?

 

Baffles in any race car catalog. Summit comes to mind or maybe Jegs.

 

Here's a couple options on the baffles...

Storebought:

I'm soon to be running a set of the storebought ones on my 406. I'm dying to hear it run. Wish I'da found the tech post before we bought them though.

 

Daddy said he use to stack washers between the flange and the cap

You should change you handle to "No Skills" or "No Hot Rod" or "Can't Read" or Haven't Posted an Intro" or sumthin'.
