I forgot to ask you this, but do you run headers? I'm thinking those could also have helped to deepen your exhaust up somewhat. I'm thinking about getting either headers, or one of the very few available cams for this engine next. I will probably go with the headers, just because exhaust mods are my favorite thing to do to my vehicles. I'm wondering what they will do for the tinny sound I sometimes get though. I was also curious what putting a glasspack before or after each of my mufflers might do for me. It seems like that might help to tone my exhaust out a little bit. Maybe that's why some people refer to glasspacks as resonators.
