Believe it or not, I'm actually looking for a muffler on the quiet side. After my engine swap I intend to run either mechanical or electric cut-outs but I'd like to get a very liveable muffler that doesn't drone when I'm driving on the highway. Since I'm using cut-outs I'm not too concerned about performance when it comes to the actual muffler but I don't want them to be too heavy either. I know there are plenty of companies that make performance mufflers but when it comes to regular mufflers I don't know where to start. Any suggestions?
