4" silencer

Yep I have two of those in my system, using the burns as the back box.

 

No matter what you do the 4" system will never be quiet. I have a bung to put in the Burns be need a different map to run it as the back pressure causes the mixture to go rich.

 

I found that the bung had a marked effect around 80 mph, when before the whole shell seemed to resonate, a tad uncomfortable.
