I just recently added Magnaflow Hi-Flow metallic spun cats and a Magnaflow cat back system. Problem is I can be heard from a mile away and I want quiet. Tried a Dynamax muffler today and it was no better and perhaps worse. And while I know most of you want that deep rumble but that's not what I'm looking for. Based on the collective wisdom of the group what is going to make my vehicle quiet. I've been told that with the cam and KB I'm probably looking for the impossible but I'm optimistic. So whose muffler should I bolt on next? I want this to be a real sleeper.
