Anyone else's turbo do this?
 
I noticed my exhaust is shaking thus causing a weird sound when I accelerate hard cause of the vibrations. I have a fabspeed exhaust system I had them install but I also had them cut out the secondary cat and weld on a replacement pipe. Not sure if that caused this issue.

The exhaust shop told me it seems like it's my car having a slight misfire. No check engine codes or anything. It has 90k miles and I did literally just replaced the coilpacks today cause they were all cracked. I figured that might of been the issue but still doing the exhaust dance lol

just found out my crankcase check valve has a vacuum leak. I wonder if this could be causing a slight mis and making the exhaust shake like that? ordered parts already.

Did the cat bypass eliminate the stock hangers? You need those, buddy.

OH MAN! The original hangers! Where are they? **** like this will ruin exhaust flexpipes. Your "mechanic" did awesome job. Tell us where to locate this engineering genius, so nobody else ****s up his car.
