I have a magnaflow as well. Not sure what you mean in the rest of you sentence. Mine has a much different sound and the after market exhaust tip I got weld on to it as well, makes it sound more deep with the exhaust tip.
I'm looking for more hp, with a little more added rumble which is why I was considering a short ram, so I'd get both those things vs just the drop in filter which would only give me the hp.
