hey guys, my mate asked me to put a pipe straight down the middle off his cat so its one pipe, just looks like there is a cat there.

I have a the cat and some 3" Pipe but it isnt sliding down the whole, how would i open the cat converter, put the pipe down the middle and put it back together.

I Have a every type off tool needed to do the job, just dont know how to wink.gif

Not offering help, just going to mention..

Even if that cat *looks* like its there, you can smell that there isnt. The cops or defect stantions or road side people have machines that can test that your cat isnt working (like same as bashing out the honeycomb stuff) and you *will* be slapped with a $10,000 fine. Not kidding.

has anybody ever actually heard of anyone getting booked for it....?

also the $10,000 fine im pretty sure is only to a buissness if they do it for you, im pretty sure the fine they can thwack you with is less than $1000, and i doubt it would be onj the spot, it would be a proper emmisions check at EPA, at a later date....

you need a smaller pipe, or you need to grind the inside of the cat out by how thick the 3" pipe is (as the cat is 3" internal diameter, as is the pipe) you should be able to easily grind the couple mm out of the cat, but it will take some time. Thats what i did for mine, but i wouldn't recommend it, as while yeah it does make some power difference, it also makes RB's sound raspy and a bit bomby, im getting a highflow just to make it sound better, and getting a test pipe made for track/strip

Go easy on our little planet please =)

I'm pretty sure i read somewhere that its almost worse for the planet (i.e. ozone layer) having a cat (with unleaded) as it produces random fumes (no2/sulphur?) but they have them to reduce smog etc caused by carbon monoxide, so in city's etc it reduces smog, but in the long run it kills the ozone.

don't know how true this is, google it...

but yeah, definitely go a highflow, just for the sound, you drive an RB - you dont want a 4 banger tinny rasp :laugh:

    • I know it's an entirely different engine, but I noticed practically 0 difference removing or adding 2x 3in (5inch body) 400cell cats (one in each bank) with regards to sound. So changing the cat to change drone I suspect will have very very, very, very, very, very very minimal impact.
    • 200 cell cat will probably help. Do you have room to tee off a Helmholtz resonator anywhere along the exhaust? These can do wonders for drones, with a little experimentation with regards to length.
    • The car revs up through the gears much better/faster now, and fuel consumption doesn't really seem to have be affected either on a Hwy cruise, which wasn't expected  The FAB9 intake manifold has been problematic sourcing though, I've contacted Plasmaman to ask about their intake, which you can get different runner lengths spec'd, and, their different options for throttle bodies  The only real physical drawback with the Plasmaman intake is how to connect it to my current OEM style airbox, as FAB9 make a OEM style back half of the airbox to suit the larger diameter throttle body, and all that is required is a 30°bend silicone pipe to mate the throttle body to the airbox Car also goes in for some exhaust work in a week or so to fit the biggest resonator they can fit clearance wise in the front pipe to help remove some of the drone, there isn't alot of realestate under there, a rough guesstimation is it will only be about 3-400mm long and maybe 90-100mm diameter, and with a 60mm exhaust that doesn't leave alot of space for the internal volume of the resonator to do its thing I'm thinking I may need to bin the "high flow" 100 cell cat for something a bit more substantial, yeah, and restrictive, like a 200-400 cell, to help, but, I have ample room for a really large bodied cat to replace the current one which has around a 4" diameter body I may look around in the recycling bins and see if I can find a massive newish cat that was "replaced" with some new full exhaust system that the local exhaust shop in Western Sydney is doing
    • Hahah look at that smile 😂 Just like those ones on IG where they compare the husband in family photos vs husband going fishing lol. I don't think I'll participate this time, clutch isn't in and also the last time I went there were too many numpties on the cruise sessions. Nearly caused a few accidents holding up people and a few guys initiating massive kerb to kerb drifts with heaps of cars right behind them. Not to mention, there were guys on the track session using it as a power cruise session.
