I broke an exhaust mount on my Stage 2, it was the Janspeed version. I just wanted to let people know that my mount cracked and I had a terrible buzzing in the car. I thought it was the heat shield, but it ended up being the mount. Of course, I purchased it awhile ago and there is no warranty or anything like that. Luckily I took it to a local forum members shop (RCHAD) and he cut out the old muffler (it was hollow at this point) and he welded in a new muffler and fixed the mounts. It sounds mean, and now I can drive again. Check your mounts if it has been awhile.
