OS .91 Muffler - Do I need the extension?
 

Hi,

The OS .91 comes with a three piece muffler. The middle piece seems like just an extension. Or, does this have to do with performace? I would rather leave the middle piece off.

What would be the impact?

Thanks!

I don't know a direct answer to your question but don't know why they would put that section in there if they didn't think it was needed.
I suggest you ask in the OS support forum and get their opinion

You can still make up your own mind later. :D
