Some DIY exhaust dual port muffler components 

You will receive what you see in the first 5 pictures.  

**The last picture above is what you will have once you cut them.**

Stamping for 3 dual port mufflers.

Stainless steel screen.

These are nice, because you can cut them and put holes where you need or want them to be.

Cut's very easy with sharp tin snips. 

Feel free to ask questions. What you see is what you will receive.

No screws or rivets with this kit. You can use whatever you prefer, or whatever you have available. 
Rivets or screws both work great.
