Sure np the rwaaap noise your hearing right before I shift is the wastgate opening at 35psi don't have anything to do with the exhaust set up it did it with my stock side exhaust straight piped to this stock turbo only does it far as i know my new turbo dont do it but its got one hell of a whisle

[@GarageOperator]

Ethen as far as I know the rawaapp noise is from the turbo it did it with my stock he351 turbo and 4"stright piped. But now that iv changed my turbo it don't do it no more. I miss that sound to man

[@ethancook9902]

I asked that man cuz the only reson I haven't gotten stacks is I thought the blair or rwaaap!!! Right before you shift didn't happen with stacks I had a 5inch tbe exhaust that did that right before I shifted but I got a new truck and I'm needin ideas thanks though

[@ethancook9902]

So that rwapp or blaring is the wastegate openin I thought it was back pressure
