Further to the point of the thread, i have a mate who purchased a car that has no cat. The cops pulled him over to issue him with a speeding fine. The checked his exhaust by having him rev his engine. What they did while he was doing this i do not know BUT he drove away with just his driving infringement.

Probally seeing how loud his exhaust was at a guess.. its a bit hard to tell if there no cat in there unless you nosed is set to pick up excess emissions, tho a bad tune could also have the same effect as no cat..

ok, no cat will give you a slight performance increase, less restriction and all that, yes it is smelly, yes it is illegal, no i don't advise it, the 10k fine is real as far as i know, but i belive its an EPA thing, not something the DOT hand out, and unless you've really upset someone i seriously doubt they bother, id say its more a thing that they use on companies than individuals..

if your cars a daily runner, leave the cat in, you'll do yourself and the eviroment a lot more good and less hassle if a cop does pull you and spot it, unlikely but hey it happens..

if yours ia a weekend racer and you use fancy stuff like antilag, then get a cat replacement pipe, lots of antilag usually melts them after a period of abuse, but throw the pipe in on the day and pull it out that night, can probally get them made up for about $50 at your local exhuast shop with the right flanges, and take about 10 mins to swap in and out..

    • The issue now is the 'fuel cut' while driving, and when it happend, it does not stall. This, I did not test the fuel pressure while driving as I cannot with a fuel pressure gauge. I do have Nistune logs, yes. I have also replaced the MAF Sensor.   Also related to the FPG Fuel Hanger – I just realized that I need a Deutsch Crimp Tool to crimp some cables for the FPG Fuel Hanger. Need to purchase additional cables as the kit only included 2, which are for the float. FPG has not responded to my emails so far since purchasing. I thought about taking it to someone and having it done professionally, but I am reluctant since everyone I took it to messed up in some way.  
    • There's a good German place in Brisbane if youre up for the drive 😛
    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋
