on3 noise

Has anyone noticed a rattling sort of sound when on accel or hard decel?

I have the 1st gen on3 kit and when accel building boost it makes a terrible rattling sound until I build boost then it's gone?

I have checked every pipe nothing is touching, I am starting to think maybe I am hearing exhaust noise from inside the hot pipes?

YES! If it is at all similar to the 2nd Gen kit, it's the downpipe exhaust that runs through the driver-side control arm. I had to install an exhaust hanger there and the marble-rattle went away. There is a really long section of exhaust pipe after the turbo before it reaches it's first hanger. Putting that one in helped stabalize it.

I see

I noticed that and I made a temporary hanger with some steel pipe support strips but it didn't help me. It is bad enough that if I don't fix this horrible racket I'll have to take the kit back off for my sanity.

Did you use a rubber hanger? I was thinking it could be an exhaust leak but I'm spooling right on time so that kinda rules that out

Do you by chance have a photo of the hanger install as I am also having this annoying rattle-pinging sound on the drivers side, but it is not detonation pinging from the engine?

i had a rattle that was driving me crazy and it ended up being one of the plugs that are in the multiple bungs for o2 sensors.
