Ok my car has been making a rattling noise from the cats and it just got even worse today now my car has no power and it sounds different. What could be wrong with the cats they are stock so could they have fell apart inside ? what cats should i get and where is a place to get them for cheap ???

 

Sounds like the "honeycomb" block inside the cat broke apart. I just got a new cat from summit. Its a Catco and its a high-flow model. I paid about 95 bucks shipped to my door. I've heard theyre pretty good. It looks good, just have to get it in. You can get a direct fit model for your car, they might be a little more expensive, but you wont have to weld or clamp anything.

 

I would lose alot of power if the "honey Comb" broke a part right ? cause my car has like no power at all now and i bogs alot rpms dropped below 500 could it be clogging my exhaust that bad ?

 

It most likely is, It could actually be causing turbulance in the cat also which would also cause power loss. If the cat was making the noise for a while and the power loss just suddenly happened, it might be someting else, but reguardless, the cat needs to be replaced if there is ratteling inside, so give it a shot.

 

the cat was making some noise and then the noise got worse and then it really started losing power so its most likely is the cat atleast i hope it is

 

More than likely your honeycomb "anti-pollution" element has worked its way loose. Happened to me also. Ive seen them get so bad that they turn sideways, blocking exhaust flow and causing major performance problems. My solution...stick a bfp (big f@%king pipe) in the opening and ram all the honeycomb out, leaving a hollow shell that will still pass visual emissions inspection. Your car is too new and EFI controlled so dont worry about failing. (unless you live in CA)

 

Since i have no money for new cats im gonna cut them off for now and clamp a pipe from the y pipe 2 the cat back. I know its gonna be alot louder but is it gonna be so bad that i get pulled over ?

 

With a flowmaster its gonna be a considerable noise difference. Mine was quite a bit louder after gutting my cat, a buddy of mine did what you are planning on doing and his car was much louder than mine. (boy, the simple days of stock )
