My Jeep is supercharged, so I fabricated a 3" straight exhaust with no cats to a muffler with a turn down. At first, I had a Thrush chambered muffler, and it sounded like a V8 at idle but had AWFUL drone on the highway and was wayyyy too loud. I now have a Borla Pro XS straight through muffler, which is far quieter, despite being a straight through higher flowing muffler. The Borla doesn't drone and isn't obnoxious, even with no cats and 3" pipes. The Borla doesn't have that V8 rumble though.
