As previously mentioned, I replaced the stock pipe with a DG, saving weight, improving performance and safety. The safety was from the louder pipe – people often hear motorcycles when they can’t see them, especially louder bikes. So here’s a before and after look at the pipe replacement, using video with sound. As it turns out, it’s not that much louder with the DG, but it’s a deeper, throatier sound. It is louder, but I didn’t want to rev it like I did in the stock pipe video and bother the neighbors (any more than usual). Bottom line: A good mod.
Here’s the “before” of the stock pipe.
Here’s the video of the DG pipe. Now it sounds like the thumper it’s supposed to be.
