^ Yup, my thoughts exactly.

quick question, if u shake the whole cat back and forth does the inside wire part shake around at all(from one end to the other if u move it back and forth), or is it totally fixed and not moving? thanks

^what inside wire? Last time i was shaking it it shook all the way back to the motor and the other side starting shaking too.

Yeah I probably could yank it off, thanks for the help, I wouldn't have liked recieveing it half bent lol


If you mean with the HFCs not installed then no there's no noise

yeah of course i mean when its not installed...when the cat is out of the car if u shake it around, does the metal wire part inside the actual cat shift around or does it stay completely still..

It should sit snug inside the canister. If it doesn't I would suspect the vibrations will cause it to break up. Every cat I've ever removed was snug as a bug in a rug.

Nope mine don't make any noises

Mine stayed completely still.

well heres my passenger side high flow cat...berk is going to warranty but

uhhhh wtf?!

tell me about it...been on for a month, i am tuned my a/f is 11.8 rock solid with my vortech kit and i have had zero misfires..idk..
driver side is rattling around too so im sending that one back as well...just posting this up for people to look at with symptoms like car sounding different not having the same growl...hard to explain...got quite a bit quieter still had some power though is what got me, but idk i didn't go make hard pulls or anything so hard to tell if it lost power, ran fine though, just sounded different..berk is great to deal with though let me say and they are fixing the problem..

what do you mean sounded different and why is it all blue?

Looks to me like they melted. EGT's got too high for them to take and they broke down. I've not seen it turn blue but I've not seen a failure on a 'high flow' cat either..

melted cat

its not blue...its just from my flash on my phone....and it def. didn't get too hot...i havent tracked the car or taken it over an hour drive in a long time, or even beat on it...i went to the store came home on the highway made a 2nd, 3rd, and 4th gear pull and came into town to realize it just didn't sound the same and then put it away and pulled them yesterday morning..

as far as sounding different it, was just quite a bit quieter all of a sudden, and didn't have the same deep growl and little pops on deceleration
