Long story short I was having boosting problems and found out my cat clogged. Took that out and now my car sounds like this. I'm not used to it sounding like this what do you guys think? These are 18-20 ish psi pulls. The car is slow as **** I wasn't shifting at high rpm on purpose since I know something is up. I just haven't had the time to check the car so just seeing if I get any insight.

No boost leaks and no shaft play I've checked all the basics. Next thing up is I'm going to check the turbine and boost controller it almost sounds like the turbo is over spooling.

Over spooling? It that a good thing? It spools fast with no shaft play.

Cleaning your cat increases airflow which leads to faster spooling. If you haven't gone to 3" exhaust this is example of what the benefits are.
