Just installed an Evolution Racewerks DV pipe and I'm now hearing a faint whining sound when the turbos are spooling up on boost. The noise wasn't there before but I think it might be normal since the stock DV pipe has a sound suppressor tube that runs from the main part of the pipe and the EV pipe doesn't have that. The noise isn't loud but my only concern is that there could be a leak. Anyone else experience this sound after installing a DV pipe? Is this normal?
