If'n you're looking to get rid of the loud "brrraaaaaaaaaaaaap" coming from the glass pack, and want to still have dual exhaust, why not shove two repop stock mufflers under the truck. I bet it would sound cool. Split exhaust on an inline sounds good. I had fentons and glass packs on my last truck, it was a bit too loud for me as a daily driver. But it did sound pretty sweet.
