Just got the car back yesterday, they replaced the turbo, charged me diagnostic fee for the noise and maintain that it was caused by the freyed flex connector coupler in the exhaust even though its not making that noise anymore....
Goto exhaust shop this morning to get that coupler replaced and they told me I'd be better off not replacing it since its not leaking at all, and it could last longer than what they would put in there to fix it considering OEM is stainless and his replacement parts aren't. Sounds like even more of a reason to get downpipes IMO.
Only issue I seem to have is when the car starts and idles for a few minutes to heat the o2s, when it actually cuts over to closed loop it seems to maybe stumble a little or hesitate but after a few seconds its back in business, drives fine from what I can tell.
