After having fun at the track and on the way home, I heard something popped off of the car, and the exhaust sound becomes much quieter now. The car also doesn't make much power as like before. I have j's 70rr which is very loud with big drones that I can't talk to the person next to when cruising on highway, but I can fairly chat well now.

I couldn't find any leak on the exhaust pipe (from test pipe to the rear end), so I suspect exhaust manifold. Right guess??

 

Clogged cat?

 

^^ what he said, your cat may have broke? unless you have a test pipe..

 

I don't have a cat

 

Well, then prob not your cat....
