Did you listen to the video? It sounds way too metallic to be a loose particle, if you ask me. It also goes away at above the 3K mark.

Well Arnold, you really need to get under the car to figure out exactly where the sound is coming from, to be sure.. but luckily Tony is helping you out since I guess not everyone has a race jack and jackstands like I do..

That is exactly what mine sounds like and the sound in my case is definitely coming from inside the pipe (the pipe is not hitting the car or anything). Tony is sending me a replacement as well so I'll keep you updated. It stinks that this is happening to some of us, but I guess that's how first production runs are sometimes.

The reason the sound goes away once you rev it up some is beause the ART Pipes (and exhaust as a whole I would imagine) vibrate at different intensities at different RPM's. Around 2000 RPMs (or a cold start) they vibrate a lot.. so that's why the rattle is worst there.
