From what I can tell the Fusion has an extra resonator compared to the Mazda6, to me I think the Fusion exhaust is too quiet, although I don't want a loud aftermarket sound either. Just more of the v6 growl coming through the exhaust. Right now there seems to be more intake engine noise than exhaust noise. I'd like to remove the on resonator, I've done it on other cars with success, figure this one will likely benefit too. I like the look of the stock mufflers, so I think removing the one resonator should be a cool way to go. I've never heard a mazda6 exhaust note, is it any different than the Fusion's ?. Any opinions would be cool. thanks

Seeing as there weren't any replies I ended up having the work done. I like the "small" upgrade. We removed the resonator and put in a straight piece of stainless pipe. The change in sound is minor but nice. The sound is a bit deeper at idle, and you get a bit more resonance sound at the rear end, but inside the car there isn't any excess noise. You need the windows open to hear the difference, it is just a bit more resonanace sound out the rear end, more of a v6 resonance as the rpms rise and drop, but it is a nice sound. No real extra sound entering the vehicle cabin. As far as performance, the car feels like it pulls harder on the top end around 4500 rpms and up to redline, again without any added noise.

The stock resonator wasn't too bad in terms of construction, it necks down perhaps a 1/4 inch on the inside but that is about it, the perforated pipe probably disrupts air flow a bit. I'm happy with the change, as I don't really want a loud exhaust, I just like to hear the v6 resonance a bit more, and that is what you get. I think it probably sounds more like a mazda6 because I believe they don't use the added resonator that the fusion uses. The sound change is more evident from outside of the vehicle rear end than it is from the interior, and the exhaust note is really smooth sounding, whereas the stock setup has absolutely no sound coming out of the rear end. I am positive my wife won't notice the sound change when I pick her up from work tonight, and trust me she would notice just about any change made to my vehicles. he, he, :).

Well that's it for now.
