i think my cat collapsed on itself, i suddenly cant boost anymore and i had checked everything. the cat is a car sound ceramic cat and its only about 3 years old. one of the things that leads me to believe its the cat is that the sound decibel seems to have gotten softer and i've notice that during med to high revving white sand looking grains come out. i am going to remove the cat on sunday and wanted to see if anyone out there believes it to be the cat as well.

 

If you have a material other than exhaust gas or carbon coming out of the exhaust, I'd say it's worth a look.

 

The cat blocked on an escort that I had ,so I just bust it out but be careful it is very dangerous and could end up makin you sick if you touch it .It looks like honey comb

 

also just know a piece could have broken off and got stuck in the piping from the cat back so you are going to have to check the rest of your exhaust system as well
