I just recently picked up my 99 SE HOT Vert and have a quick question.

I hear a quick clicking type noise, almost like a plastic babies rattle but consistent when I down shift and let the engine brake. Obviously creating a back pressure scenario in the exhaust.

It definately happens every time and there is a short 1-2 second delay before it starts. (e.g. Cruising at 3000 - 2500 rpm and letting off the gas initiating an engine brake, wait 1-2 seconds then noise starts)

I did put on a new MP downpipe but the noise is definately seems like plastic noise. Is this the Blow Off or something turbo related?

Oh yeah, I think I may hear the same thing briefly while shifting during hard acceleration but I could be imagining that.

Any help would be greatly appreciated thanks
