Sounds like something broke loose inside. Any ideas? I have pushed on it and pulled on it to see if it was the case or somethnig. Has to be internal.

 

looks like one cat is backwards. last i checked the tubes coming off a cat are for air pumps. but the tubes should face forward

second sounds like the ceramic came lose and is bouncing around inside.

easy fix remove them and hollow them out

 

Broken catalyst!!! Time for new kitties.

 

need new cats

i'm pretty sure those re just mounts. as they look to be after market cats already

 

nope!!! tubes on cats are for air pumps. its so you can have air pumped into a cat to help cool it so it doesnt heat up and melt and get clogged. cheap cats have those along with older stock production ones

 

when it makes that noise it means you need to replace them with straight pipe

 

Or if you just listen to it a while they will hollow themselves out.

 

Guy behind his truck will love that!! Blowing huge ceramic chunks all over his windshield.

 

ok, it just looked solid when i seen the vid. but i can't tell. so i'll take your word for it.

 

THOSE TUBES ARE FOR AIR INJECTION SYSTEM.... BUT NOT FOR COOLING THEM.... IT WAS TO ADD MORE OXYGEN SO THE CATS WOULD "LIGHT OFF" QUICKER... OR GET HOT FASTER.... THEY WERE INTENDED AS ANOTHER WAY TO REDUCE EMISSIONS SO THAT WHEN YOU START THE VEHICLE THE CATS WORK QUICKER...


AND YES YOUR CATS ARE YOU NEED TO REPLACE THEM OR EVENTUALLY A PIECE COULD LODGE ITSELF IN THE OUTLET AND CAUSE EXCESSIVE BACKPRESSURE WHICH WILL MAKE IT RUN HORRIBLE
