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.

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.

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???

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

    • Hey keep the ideas coming, I'm always keen on projects! But, problem fixed!  I got a cheapie ozito scope from Bunnings and had a good look in and around the bearing and sensor hole. I couldn't see a smoking gun but the bearing looked a bit strange, especially when comparing with a new one. I thought the cover had come off the bearing magnets.  Sorry for pics of a screen, I didn't have an SD card.     Good thing I had the old one to inspect. So, given I'm like a pit crew with wheel bearings and luckily I had a spare bearing because I f**ked up my parts order, I decided to just smash it out. Got the old one out in about an hour. So much easier when the parts haven't had a chance to rust together yet. 😂 And, well, found the problem.    In the second pic at about the 8 o'clock position, you'll see what I think is the tip of the old sensor.  The new sensor has definitely been rubbing but it's all intact, just a little shiny so I'm hoping it's fine.  The car brakes perfectly now and no errors.  I think the job took about 2.5h in the end. 👍🏻 I really appreciate the help in here as usual. Thanks guys.
    • I was only looking because I saw some drops on the ground but it wasn't alot. Recently had it serviced will ask the mech to confirm. Find it strange that it looks standard though, can see in another photo of a random box 
    • So...not sure if you know if that has always been there or why you went looking. It could be old damage from a clutch explosion, or even just the gearbox got dropped somewhere along the line. Basically, you should seal it up to stop oil and dust getting into the bellhousing, but it doesn't matter too much and is not structural. I'd suggest something like a glob of JB Weld. BTW what gearbox oil are you running, I would guess the breather has been spewing it everywhere.
    • Hey Duncan thanks for your reply. Sorry mate I know the photos are shit.  Took another photo for reference. Seems the casing does have a hole in it looking on the net, fluid seeping out. Added a photo   
    • Very hard to make out what you mean, is it the squarish hole with redline shockproof (probably) under it? Is that pic from on top of the engine with the firewall to the left of pic and engine to the right? Either way, spray the area liberally with degreaser and try again, maybe circle the part you are worried about
