Here's an update for my issue:

My stock EJ205 02 WRX motor went at 123k miles. I replaced it with a brand new 2010 EJ257 short block (Hybrid, using 02 WRX heads). During the swap, I was tempted to change out my Exedy Stg 1 organic clutch and ACT 14 lb. flywheel for stock units, since I am too sick of that awful deceleration noise. I was tight on funds, so I decided to just stick with it for my EJ257 swap. I was hoping possibly I wouldn't have as much noise with the new short block, but upon completion, it was still there. But, some good news came out of this. I decided to try staggering my tire pressure to 36psi in the front, and 32psi in the rear, and LOW AND BEHOLD, my deceleration noise is near GONE! It is probably 90% gone, and I can only hear chatter at very certain RPMS in 2-3rd gear. I was skeptical about this at first, but I'm glad I tried it, because now it's not nearly as loud! I'm loving my new engine and nearly no deceleration noise!
