I did at first. What it was is that if you are looking at the car from the back the exhaust is getting it's rattle from the left side of the exhaust. If you go underneath the car and shake the exhaust alittle you will notice that it can touch. It touches about a foot or so back from the bolts that connect to the downpipe. I just adjusted mine so it would stay farther to the right. Just pull the exhaust to the right and adjust your hangers. I know this all might sound weird but it worked. It's hard to fit that huge pipe in there

Just shake the exhaust back and forth and you will hear the metal that it can touch.
