    Or normal people. Remove them for an extra 3rwkw and extra mang.

    The cats are only there to reduce emissions, nothing else. Not create back pressure or any other fairy tale.

    The engine management system is designed around them being there. The car will run better, perform better and use less fuel without them, as long as it is tuned to suit.

    Can you remove them? Sure. You will need to get the part of the tune that reads post cat sensors deleted though or you will be throwing all sorts of errors.

    If it is illegal where you live, then it's totally up to you whether you run that risk or not. Here in Australia it is illegal to remove cats if they were fitted from factory. The reason we have cats in the first place is because pre cat emissions killed all the unicorns. Pretty sure all the people that have either removed their cats or smashed the guts out have made the Western Black Rhino extinct as well.

    So, on a more important and interesting topic.

    Have those Western Black Rhinos gone and gotten themselves wiped out?

    Apparently, it has been declared extinct because the last official sighting of one was back in 2006.

    Probably. The only thing that distinguishes the Western Black from the ordinary Black is location. It is "believed" to be genetically different, but we'll never know now. If people are encroaching on an animals habitat, most of the time the animal moves.

    I heard removing them is good for fuel economy and engine breathing. Here if your car blows a huge black smoke , no one cares for environment even the police.

    HSV doesn't have high flow cats.

    Thanks.

    You think I made stories?

    I have more than one car. All of them are Holden. I used to have 11 cars, but now I only have 3 cars.



    Man, it's just a question.

    Check Engine light came on and I used my scanner tool and the code was P0420. I went to the dealer and they says "the catalytic converter is clogged and I need a new one". It's an expensive part, that's why I asked this stupid question.


    Actually I don't live in United States. :smoking:


    Why are you guys don't believe I own a HSV? Do you want me to prove that? I will make a video today.

    get the system done properly, stop being so damn cheap.

    good extractors and a properly set-up system will outstrip your backyard job.

    And it was a pretty stupid one at that. Your car came with them what makes you think you'd be able to remove them.

    You claim to own 3 cars, surely you can afford to do headers and cats on your HSV as opposed to just an all noise cat back. Cats are cheap if you're just replacing the standard POS.

    it's legal where I live. I'm going to smashed the guts out, but the question is, do I really need to tune my engine?

    Because where I live the Dyno tune places have a bad reputation. It's really cheap, but they damaged many engines as I heard because they don't have any experience. This car has 64,000 km on it, but the engine has been replaced. It's actually 28,000 km. so I'm a little afraid of tuning my engine.

    Thanks bro.

    You really only need to have the part of the tune that reads the sensors after the cats turned off. Otherwise, put up with the light and chimes when you start your car.

    You've said to different things about cat removal, you need to figure out your BS story.

    What country do you live in exactly.

    When I said "I know it's illegal to do that" I mean it's illegal to do that in Australia.

    it's legal where i live (Middle East, Oman).

    I don't understand. Why are you so upset?

    thought they were Chevrolets over there,if you want people to believe you maybe you should take a photo of your vehicle and post it here,then people might believe you more
    the removal of cats won't give you much of a power gain,why don't you just buy a complete system and install it yourself,

    People in australia know its illegal to remove them, know need to point it out. If its legal where you live why not just take it out and save us all the hassle of ripping in to you.

    they sell x-force in oman?

    anyway dont bash the guts out, itll drone as mentioned. get a proper length of mild steel tube to replace the cat which will make it sound normal.

    there are noticable power gains to be had from an R32 GTR from a de-cat pipe. an NA commo i dunno about.
