well, i was on my way home tonight and i just got off the freeway.
approaching the stop light @ the end of the freeway, i let my foot off the gas.
- to the punch : it sounds like someone is throwing marbles in engine(sort of). only happens when at 2k RPM or higher.

the 1/4 doesnt have patience for a ST.... so we make them ST-T's so atleast we'll sound good going slow.

Hmmm, difficult one to diagnose without actually being there.
As above, does it happen in neutral? If yes, the you can usually rule out transmission.
As above, I would be suspecting a bearing, possible big end or crank journal. Only real way is to pull the bottom end apart to check. A pain to do, but better now than to have soemthing fail completely at high revs which could result in more damage (and be costlier).
Other option is to take it to a trusted mechanic who would be better placed to offer a diagnosis on teh spot.
