muffler question
There are also collector inserts you can put in the ends of your headers that will quite it enough so its legal (and they have a spiral effect that is suppose to speed up the exhaust for a scavenging efftect), but still sound awesome. Then you dont even need mufflers. Thats what I was running for a good year or so, saved some weight too. I am now putting on a exhaust system with DynoMax Super-Turbo mufflers, as I got tired of the drone of the loud exhaust inside the car during long drives.
Youtube also has some good mopar exhaust sound bites.
