So a YouTube video or two shot with a **** low quality microphone will replace people's first hand experiences with their own ears? On top of that, i asked how the x-pipe sounded, not the sound of dyno rollers spooling up and down.
The link provided answered 1 and 2. I stated there are youtube videos of 3.7 offroad x pipe sound clips, just SEARCH! Some of those videos came from members on this site and the sounds not that bad. Again, do some research yourself. You already suckered me into giving you the first link! If you're okay with everyone else doing the work for you, just sit back and relax then
