Have you heard either setup on a 3800? I mean, it seems kind of unusual to base a choice of a brand on how it sounds on a different vehicle/engine. Honestly, I've heard very few aftermarket exhausts that don't have the raspy sound at high rpm with the 3800, but I didn't stop to ask them what they were. I'm sure some members here with the products in question could chime in and be more helpful than myself lol.
