Basically, in short, the car sounds like a lawn mower. That's the best way I can explain it. It tends to go away at higher RPMS but for the most part (especially rolling the car into 1st gear) the car literally sounds like a lawn mower. I sourced the problem coming from the passenger side of the engine bay. I have already checked the following:

- V Clamps on the turbos
- down-pipe fitment (the downpipes aren't touching anything. I even checked the heat shields.)
- waste-gate rattle (its definately not this. Although my turbos are suffering from this you can distinctively hear the difference between both as I am driving.)

If there is anything else I should be checking please let me know. It is extremely embarrassing to be driving around like this. Thank you.
did you ever figure this out? having the same issue
