I modified a stock o2 housing today for an external dump. My question is, Should it be loud even if youre not boosting? Its almost like my wastegate is open all the time, even sitting at idle and reving the motor. And yes i welded shut the wastegate pasage of the housing so exhaust gases cant get out of the dump tube, just wastegate gases. I weld all the time at work, the welds are good, the passage is closed... Is this normal? I thought it should just dump out of the dumptube when the wastegate opens at full boost... Idedas??
