IM HEARING A STRANGE NOISE WHEN I LET OFF THE GAS. KINDA LIKE A CLUNK. IM PRETTY SURE ITS MY STOCK DV. ITS NOT LIKE A BOV SOUND OR ANYTHING, IT JUST DOES NOT SOUND CORRECT. I NEVER HEARD THIS BEFORE SO IM NOT SURE WHAT TO DO. ANY ADVISE??
But yeah, it could be your stock dv. It is basically known as a "throw away" part. Either pic up a new one from your dealer/online parts shop or go another route and upgrade the stock DV in hopes of longer life. Stratmosphere, Bailey, Forge, etc. all have decent DV's.
