Sounds like something isn't connected right. Check the downpipe as well as the crossover. What kind of turbo do you have? For the ATS design the downpipe is just pushed up into the turbo outlet, there isn't really anything holding it in place there, just a small bracket down lower. When I first put mine on, I didn't have the bracket in the right place, or tight enough, and the downpipe slipped right out during my first test run. See if the exhaust gaskets might be leaking.

i had to torque the crap out of my crossover pipe flange nuts to get it to seal up good. Once i did i found my boost will get high and stay high, no leaks here. Almost sounds like an exhaust leak. Can you try to describe the noise? like a clicking, rattle, clack, etc? maybe a vid so we can hear it?

with mine, only when going slower in top gear could i hear the clicking sound, hard to describe sound but yeah when i rolled WOT, it was drowned out. So it is entirely possible, or it could be rubbing from being misaligned, not poking at you, just hoping to help ya out bro!

id look at them to make sure they arent bent, dented etc and then yeah sure, clean them up nice, and coat them then clamp the hell out of them haha. if that doesnt work then it may be timing or something rubbing or similar.

Not sure, just guessing but it dang well sounds like that. My case is strengthened in the fact that it wasn't making this noise with the old crossover. I'd check just to make sure cause if there is, you'll mess up your whole impeller, and possibly the bearings and compression wheel.
