I don't know what the configuration of the factory titanium exhaust is. If it's an x pipe or has a muffler integrated........If it does have a muffler it's probably a little more complex than the x pipe so it's probably a little heavier. As mentioned the x-pipe on my car is a little under 7 lbs without some tips on it that should add a few ounces but not much.
Brian,
Other than the tips the factory Ti exhaust looks almost exactly like the stock stainless exhaust, muffler and all. It is not an X-pipe. So the info given to me has to be off as that would put the Ti exhaust at 9.5 lbs with that big muffler. If a Ti X-pipe weighs 7 lbs with no muffler, the factory Ti must weigh at least 15 lbs with it's muffler. And there should be a noticeable difference in sound between the stock exhaust and an X-pipe at least at full throttle. Ford had no muffler on the grey 2016 GT that Raj drove at Le Mans in 2016. The GT would not pass the maximum decibel level for new cars so the muffler needed to be added to quiet it down.
