I just had mine installed this morning. The exhaust note sounds good. A little louder than before. There's a rattle though. Sounds like it's coming from the front near the exhaust manifold. You can hear it when you're outside the car or with the window open. It's not as noticeable when the windows are closed. Did you guys notice this? The OP mentioned hissing and rasp...I don't hear that, but I definitely hear rattling. I talked to the mechanic and he said all the bolts were tight including the ones that go on the support pieces. No rattling before the install. Anyone experience this? Bluestyle also has a thread about ERZ HFCs, so I'm going to ask there as well.
