Is it good to remove catalytic converters?

[Hussien]

Hello,

I have a really simple question. I own a 2008 Ve Hsv LS2 and it has only 64,000 km on it. I just my installed XForce 3 inch Cat-Back System.

I would like to remove my catalytic converters. I know it's illegal to do that, but the question is

Would my engine breathe better than before when I remove the catalytic converters? Would the fuel economy be better or worst?

My car has two catalytic converters.

Thanks.

Well as the car is set up to have cats , probably not , you can get high flow cats fitted , which will keep it legal , actually , wouldn't a HSV already have high flow cats ??

Your car and its story changes every time you post on here. The car is the least of your problems when you can't tell the truth, can't help yourself, can't say thanks.

What a stupid ####ing question. If you know it's illegal why would you even consider it.

No removing them would be bad for your engine

Cats make back pressure with is good and without them you can/will burn out your valves. Don't be cheap a buy hi-flows probably a 200cpi cat as 100cpi cats are illegal too

And no a HSV has the same flowing cats as a Holden 6L

Because racecar.




Funny thing, my phones predictive text me offers "racecar" as a potential next word everytime I type "because" lol

Why do you want to remove them?

 

[corhijasna]

as stated they are there for a reason,just get some hi-flow cats as removing them is detrimental to your car and the environment-lol
