You are right! Thanks for the idea. I had been looking for an exhaust or eliminating the small muffler. But I was afraid my 545i would be too laud. With this mod it sounds almost exactly how I want it. I couldn't do the mod you did by making a union of both tubes that are attached to the valve in the trunk. Seems like I have a vacuum leak. Temporarily, I strap two big zip ties to the waste gate above the exhaust and it has been working fabulously. The best part is that the waste gate does not heat up enough to melt it. It is a temporary mod until I find my vacuum leak, which I think I know where it is, and hoping that by replacing a thin cracked vacuum hose in the engine will solve my issue.
