After seeing the pics posted of a 395 muffler split open, I am 100% confident the method I chose of adding the second port ahead of the factory port will get it breathing easier. The second port I made is as big or bigger than the original behind it only it doesn't force the exhaust out that funnel.
So just to clarify cuz I'm slow. You added a second port ahead of the first and left the origial port untouched?
