What's to keep someone from running custom pipes/mufflers directly from the headers to the side exits on the viper? With bullit mufflers would it still be just way too loud? I've got belanger exhaust w/no cats and it's really loud, but I can live with it. I just feel like w/all the extra crossovers and such, and smaller diameter, I'm robbing myself of 30-40rwhp on my s/c setup...Pardon my ignorance, maybe it's just not a good idea, or maybe just no one has done it...Your input is appreciated! Thanks--Andy
