Just picked up my proforce exhaust today. Took only bout 1.5hrs to install, and that was taking my time. The instructions that came with it are among the best/most detailed instructions I've ever got when buying an aftermarket part.
At startup you can barely even tell it's there. It's fairly quite when taking it easy, but give it a bit of gas and you know it's there. Only put about 10miles on it, so it's hard to say anything other then I love it so far.
Was only able to get up to 50-55mph when I took it for a quick spin, and there is ZERO drone, hell you can't even hear the exhaust at those speeds.
Here's a couple quick pics, and a short startup vid of the exhaust. I would've taked an in cabin vid, but I accidentally ran over my camera with my creeper while I was checking for any leaks
