Could A Cop Tell If You Have A Gutted Cat From Looking At It?

[jukic.j]

I just got my R33 and i'm not sure if it's my tune only or my cat is gutted out as well. I'm going to find out eventually when I get some time but my simple quick question was:

IF in the scenario I find that my cat is gutted and I replace it. Will that make my exhaust much quieter? I ask because I currently have an exhaust noise infringement and that could be an easy kind of two birds with one stone fix.

Cat does bugger all for noise. I found mine got much deeper and a bit louder with 100 cell cat than straight through, lost its crackle though

Damn, ok. I guess I just need to look into a hotdog/resonator. don't know much about that yet.

So far I've been defected 3 times for exhaust hanging too low. Its lowest at the flange from front pipes to decat. Straight 3" stainless decat.. Not once has a cop said anything about it lol..

I went through regency multiple times with a gutted cat, not once did they check it.

Wow...

There's no real way they can check it apart from taking it out of the system, and that's really suprise me if they did. But then again I'm in Vic so not really sure how tough they are.

Car was above legally loud with a 3" system with a single stuffed muffler and soot on the back.

They seemed far far more interested in my child seat anchors not being completely visible, 3rd brake light, and hole in my seat though???

and yes a new cat will make it quieter if yours is gutted, mainly reduce the drone like a resonator would.

When I got defected at bondi beach mid year the EPA were there, the inspector looked under my car (specifically at the cat converter) and didn't say a thing, I'm running a 3.5" straight pipe/decat with my compliance shell over it lol
