So I’m pretty new to the car just bought it 2 months ago and had to purchase a whole brand new exhaust system cause of rust. Bought a tubular manifold, an s280 turbo, Cobb downpipe, and an Mbrp exhaust. Got a base map from dizzy and got the car running this monday. I’ve been driving recently and notice it’s developed a kind of noise like the turbo is tapping on something? Only when the turbo spoils aswell. Slow acceleration doesn’t produce any noise. It doesn’t seem major as it’s been about two days since it started but wondered if anyone had a similar noise pop up?
