Hey
Two weeks ago i installed a screamer pipe on my stock turbo [for shit n giggles] but after it was on when i boosted it i could hear a high pitch spool noise like from a upgraded turbo. I was told it was my turbo dying by a friend. Today i put my stock dump back on and the sound was gone, do you guys think there is a problem?
What should I be looking at, intake side or exhaust side of the turbo? and what specifically should i look out for?
