Hi everyone, I have a question in the picture below is a tuned pipe on a Mac 21 motor. The combination runs like a scalded dog. Does anyone have any idea who's tuned pipe this is? I got it from a friend he didn't remember where he got it from either. As always thank you for everyone's help the picture is attached.
 
Maybe International Products..... Long gone for years...

Ray could be correct....It does look like a OPS 3280....who knows...lol
