Like a rattling noise at low speeds? Yeah that's your clutch, it's normal. My GTI used to do it with the SACHS SRE Stage 2. Had a really light flywheel. Under 2k it sounded like marbles in my trans.
It's not chatter, it's just the nature of those clutches. I have a twin disk in my vette now and it has a bit of NVH at low RPMs as well. Chatter is when taking off in first gear, if you keep the RPMs real low you'll feel the car literally chatter when it tries to engage. It will translate vibration into the cabin. If you have an organic faced single disk it would be tough to get it to chatter. The more aggressive materials, like cerametallic, will chatter if not engaged correctly.
The word chatter on this forum is always thrown around incorrectly, the noise that people refer to as "chatter" here is just the NVH from a clutch with a light flywheel.
Not so much a rattling noise. It's kinda hard to explain its kinda like metal gears meshing. This video is kinda similar, just gotta hear the actual rocks past the engine noise. It's only below about 2k rpms but its even louder than my intake.
