When I added a true split manifold and dual exhaust to my 235 I went looking for a set of quiet mufflers. I thought I wanted two long, stock type mufflers. I let my trusted parts counter guy pick them. He chose a pair of DynaMax Ultra Flo mufflers. I was scared when I saw they were straight through glass packs. My fears went away when I started the car for the first time after installing them. They have a really nice and quiet rumble at idle. I had to get out of the car and walk to the back to even hear them. They are also very quiet at highway speed. If it wasn't for the rap of the split manifold I wouldn't even notice them. They are perfect.
