Downpipe Waste Gate Rattle Sound

Anyone hear their waste gates being super loud and annoying. Like a metal can rattling around or something. Especially just barely on the throttle in a garage or next to something which bounces the sound.

I have this sound and am not sure if its a fitment issue or what.
I have had many turbo cars and waste gate flutter isn't annoying to me either.

But I hate rattles and exhaust leaks.... This noise is definitely a rattle but I don't hear an exhaust leak so Im getting a little lost with wear its coming from, I have been to lazy to put it up on a rack to take a good look.

If you figure it out let me know..... Take it to IND and have them figure it out for us...

Aloha

Yeah, I tried that too.... If it's normal waste gate noise fine but I'm going to have it checked out just to be sure and report back.

Mine is only an issue when cold and low throttle low speed. Once warmed up I rarely hear it. Wondering if something else is loose. Need to have them lift it and check all clamps and bolts also make sure they are properly torqued down. My tech is fanatical and he torques every bolt to factory or better depending on specs.

Yeah I will. It does sound just like the waste gates...but looser. I will have them check everything out this week. I remember the tech once was checking for a sound my car was making that ended up being the brakes but before we knew where it was coming from he checked the exhaust and he said he yanked on it hard in some area to check fitment and it's after that day I remember hearing it, and it has gotten worse so it must be something loose.

I believe it's the valves on the muffler. I have the Akro and stock DP and i hear the same thing on cold start. Just haven't had time to get it readjusted.

Mine is not just during cold start. It's all the time.

Sure it's not a rattle coming from a heat shield? I would have it checked out by Patrick.

That was my first guess, but I checked and its all tight unless its the second mounting point touching the heat shield.... I hear it behind me sometimes... I need to check the rear section to rule it out. I might have tweaked it during DP install.

Ok so I went to AMS and they poked around a little. I had a friend of mine upload the vids on YouTube so here are some links. The first link is what the guys at AMS thought was the problem initially and it sure looked like that was the case. It's a waste gate rod or something that has a lot of play and can be the cause of some noise under the hood but again that's normal and not what I'm experiencing. Here is the link to show the rod that is attached to each waste gate(one on each side)



The guys at AMS did something with the tension to see if this was the actual noise I'm hearing and it is not. Secondly the guys at AMS shut the waste gates so that they do not open to see if the rattling I'm hearing is wastegate related and the result is negative. Even with the wastegates shut the car still makes the same rattling.. I've been to the dealer and they can't find what's going on either... I have an appointment with AMS 8/21/13 and I will leave the car there a couple of days so they can locate what exactly is the reason for the rattling I'm experiencing... I will also drop the car off again at the dealer where they will look over it again and check all the clamps, bands and whatever... whatever I'm experiencing is not normal for sure and not because of the downpipes and apparently not because of the wastegates either. Below is a link to a vid of my car at idle and im just barley tapping the gas.
