hendrixhc 10,920 Posted August 7, 2016 Being new to these modern xg utes i was wondering can i replace the cat convertor with any cat convertor? For example can i remove the standard one and fit a high flow 100 cell commodore convertor with no detrimental effect on legal obligation or performance?

Defective 1,692 Posted August 7, 2016 Depending on cars running a 100 cell cat can bring up fault codes, on a xg I dare say you would have zero issues. 1 hendrixhc reacted to this Share this post Link to post Share on other sites
FORD_MAN 1,026 Posted August 7, 2016 yep shove a 100 cell on it, all falcons up to BF can run them, run one on my XF & AU 1 hendrixhc reacted to this Share this post Link to post Share on other sites
gerg 10,871 Posted August 7, 2016 Ford cats are reputed to have one of the best flowing bricks out there, and have a high amount of precious metals in them when compared to aftermarket ones. They can be used in a performance application with enlarged inlets and outlets.<br /><br /><br />Sent from my iPhone using Tapatalk 3 SOHCDriver, Valvebouncer and Outback Jack reacted to this Share this post Link to post Share on other sites

tpak addict 1,909 Posted August 9, 2016 Reminds me of a Pic a mate did years ago of Garfield with the caption "before .08" and another one with "after 308" hehehe Share this post Link to post Share on other sites
Slow250XC 1,513 Posted November 9, 2016 Keep it looking legit and cut a rectangle out of the top panel of the cat, don facemask and remove convertor brick, weld panel back in place. Easy as that. Of course in NZ we just replace em with pipe coz no laws against it. For bf falcons, territorys etc you can screw minicats into the o2 sensor hole which tricks the ecu ;) Share this post Link to post Share on other sites
dex 2,065 Posted November 9, 2016 Depending on cars running a 100 cell cat can bring up fault codes, on a xg I dare say you would have zero issues. Could run a o2 spacer as you do with focus with extractors that chuck a wobbly with codes Share this post Link to post Share on other sites

Mr Polson 10,214 Posted November 9, 2016 Just gut it, and leave the housing. Pleases the police that way. Shouldn't affect any e series, AU or BA(??) as they only have pre-cat O2 sensors. BF(??) and FG have an O2 sensor before and after the cat so the ECU knows if it is missing or malfunctioning. Sent from my Pixel using Tapatalk Share this post Link to post Share on other sites
FORD_MAN 1,026 Posted November 12, 2016 yep BF is like FG with O2 sensor after the cat, anything bigger then 200 cell will bring up fault code, unless you use a adaptor that has a little cat in it. Share this post Link to post Share on other sites
Lord_fahrquhar 2,580 Posted November 13, 2016 Hmmm I know if you shove a cat in your zorst you might get some baked meat smells and some meowing. Get your egt's right and the car should purr along. Having said that a regular moggoe is better than a British shorthair if chasing maximum performance from your cat. The more dense hair traps more pollutants. Failing that the ford bricks ain't too bad just have to convert them from 2.25 to 2.5 if going up size 1 Outback Jack reacted to this Share this post Link to post Share on other sites
Bullaman 15 Posted December 8, 2016 Annoying newby here. So correct me,please but I can but a set of extractors on the newly acquired xg ute and put on a system without the cat . From what I can see on the pictures on eBay I still need to screw the 02 sensor back in??? 1 Outback Jack reacted to this Share this post Link to post Share on other sites
351XD_Fairmont 604 Posted December 8, 2016 The sensor screws into the end of the extractors before the flange, and yes you'll need a cat otherwise you'll have a big gap between the exhaust and the extractors as all off the shelf systems are designed with them in mind Share this post Link to post Share on other sites
Thom 6,651 Posted December 8, 2016 You don't want to get get caught without a cat it's a pretty steep fine and 4.0 factory cats aren't very restrictive on a standard engine 1 Outback Jack reacted to this Share this post Link to post Share on other sites
Bullaman 15 Posted December 8, 2016 So I fit the extractors and leave the cat in place ... sounds easy Watch me cock it up!!!! 1 Outback Jack reacted to this Share this post Link to post Share on other sites
hendrixhc 10,920 Posted December 8, 2016 Cat wont line up. Youll need to cjop and add flanges. I went aftermarket parts was cheap and can be polished later! 1 Outback Jack reacted to this Share this post Link to post Share on other sites
Outback Jack 6,352 Posted December 8, 2016 You can have the cat that jumps my back fence for your ute...... I'll even box it up for ya..... lol +1 for leaving cat in.

Lord_fahrquhar 2,580 Posted December 9, 2016 Oh fucking lol on that one. No officer it's electric. The engine doesn't exist until you actually open the bonnet. So there's a good chance everyone's driving a blown ls but don't know it...
