I recently had a custom built turbo back 2.5" exhaust put on my car. Since the exhaust is solid I had to do something with the motor mounts to keep it from flexing and breaking. I was just going to purchase some urethane inserts for the OEM mounts. However, my friend told me that he had filled his with some decent results, so I decided to give it a shot. I started with the front two engine mounts which are covered in this article. After removing the mounts and brackets on the engine I first put some large shrink wrap around the bracket shaft to make it fit snugly in the mount. A garden hose would also work for this task. The reason this is done is to because there is usually about a 1/8" of free play in that area. I then used 3M brand window weld to fill the mounts making sure to leave no air spaces. To accomplish this I used a box with a hole in it to lay the mount on. I covered the box with wax paper to make the adhesive release a bit easier. I filled one side of the mounts and then flipped them to make sure all the spaces were filled with adhesive. After letting the mounts cure for about 30 minutes I put them in the oven for on the warm setting for 35 minutes. This made any air inside the adhesive dissipate to form a completely solid mount. Once removed from the oven I let the mounts sit for about 24 hours. At this point I felt the adhesive was cured enough to install the mounts, though, I did noticed over a few days they seemed to get even more solid while on the car.
