Bad Exhaust Install?

[NightKids]

New update: I went to Ringwood Performance exhaust today and they spent some time rewelding the back muffler part and tidied up some welds. Cost me $100, drove out and it's still making the noise! They said the noise is coming out of the muffler.

I then drove to Modproject for them to have a look and he reckons it might be my metal cat. I'm so confused!

Basically now I have the option to replace my muffler to an aftermarket one. I had changed the muffler to a stock EK4 one and it was still doing the same thing. I would take this approach if I believe that my DC2R muffler or EK4 can't handle the flow.

Change my cat to a ceramic one, i'm hesitant to do this cause my Magnaflow metal cat is brand new! I paid quite a lot of money for it.

Would there be a possibility this is coming from my Hot Dog resonator which the exhaust shop put in? How would I be able to tell of this is the problem?

Its hard to tell man if it is infact the cat, since they pretty much chucked in a whole one piece pipe.... it would been heaps easier had they actually made it into a 3 piece cat back and not a single piece... worse comes to worse, u might need to hack up the exhaust and have a look inside with a torch to see if anything wrong.... Or u could get them to cut it up an weld up some flanges, but thats even more $$$$.... an buy that time, u coulda gotten a proper 2nd hand cat back system like buddy club
