Exhaust bung.

[HugoBoss]

Any body here used an exhaust bung before? Got a 4.5'' cat back exhaust and want to reduce the droning a bit. Do these make any difference. Thought of making one myself.

I used to something like that on an old Subaru I had. It was called a 'tuneable' exhaust. There were 3 bungs something like the one you posted that you pushed up the tailpipe to get different levels of noise. They did work but I never bothered much with them

Thanks for that matey, just needed to know if it will make a difference, don't need to be much.
