GUTTED mY cAT TODAY

JoesAu · 31-12-2006, 01:16 PM

My exhaust seems to have quitened down a little since i had it done 2 years(1 muffler 1 hot dog) ago, so i i decided to take off the hI flow cat and rip the insides out. The car sounds better especially on idle its really deep now. It sounded tinny wen i first started it but after a drive its dissapeared. Can definately hear the induction way louder now it sounds great. im gonna get some1 to drive it later so i can hear what it sounds like outside the car.

yeah i had to gut the cat on my EB it went quiet and gutless as, wouldn't rev over 3000rpm, i gutted the cat, and the second it fired i knew it was fixed, and it sounded deep as too, and went sooooo much harder.

Thats great... thanks for allowing more poisonous fumes into the air to make us all sick.

BTW, the EPA have been known to visit this site and with a thread title like that its going to be interesting to see how long till you get a visit. Especially since it only tool me about 2 minutes to find a picture of your license plates on the forums.

I dont think its good to advertise what they have done but I think old cars (that should be running on leaded) running ULP with VSR lube are far worse. !!

Fellas next time dont advertise this fact.

EBFalcs · 31-12-2006, 01:27 PM

doesn't worry me, got rid of my EB 6 months ago.

JoesAu · 31-12-2006, 01:28 PM

hey didnt think about that i have a spare waiting in the shed to go in anyhow, it was only a experiment gutting the cat cos it was stuffed. Thanks for the heads up casper.

oh no not the EPA who cares. they are to busy chasing rice burners. it wont sound tinny if you put pipe through the centre of cat shell.

Nice attitude. Cats were put on cars for a reason. Namely so carcinogenic poisons are reduced so we have air quality slightly better than sitting in an oil refinery smoking cigars.

DanXR6T · 31-12-2006, 03:29 PM

I was thinking the same thing Casper, but you've already said it...

$10k fines anyone?

Eu-GenixX · 31-12-2006, 03:39 PM

i'm afraid i'm with casper on this one... without the cat there is some seriously bad stuff coming out your exhaust... you and your family will probably cop the worst of it too... other then health.. there are those massive fines as stated above...

definately not something i'd advertise on a forum.. if i ever have a busted cat.. i'll just buy a new one..

rayner22 · 31-12-2006, 03:43 PM

have fun passing rego next time, it sorta will stick out a bit

PHATXR8 · 31-12-2006, 03:43 PM

If it is so bad, then why are older leaded fuel cars allowed to run ULP without cats?

Eu-GenixX · 31-12-2006, 03:47 PM

they don't run on ULP?? not to my knowledge anywayz.. they use lead replacement fuel.. not unleaded...

Casper · 31-12-2006, 03:51 PM

Older cars are governed by the emission laws at the time they were built. Its a case of no government was prepared to retrospectively introduce emission laws on these cars as the cost to the population to replace them would be immense and the voter backlash would be equally immense.
On average the Australian car fleet is 10-15 years old. Given that ULP (and cats) were introduced in the XF in around 1987 this means that the VAST amount of cars on the road today are running cats. Every few years the emission controls get stricter and stricter so that, as time goes on, the average road fleet gets cleaner and cleaner.
The older leaded fuel cars are now the exception to the rule and, as a percentage of the road fleet, a fraction of a percent. Its simply not viable to have what is deemed a minor percent of the road fleet to be retrofitted... YET.

Its not that these older cars are not emissions nightmares (they are and everyone knows it), its that they no longer make up a significant proportion of the road fleet (and are disappearing fast) to justify retrospective emissions controls on them.

talk about being a disgrace... use your head...just for a marginal increase in your auditory pleasure you have decided to give several young children cancer..

NeishaXR8_347 · 31-12-2006, 03:59 PM

My boss has a XL falcon with a 302w same exhaust as mine but is twice as loud and he has no cats, but that said it sounds nice but when its idling you cant stand behind it without getting watery eyes and a funny nose feeling.

ill stick with my cats fitted and working.

pot calling the kettle black. so you all have standard cars with no mods or after market computers. anyone changed there cam shaft. does running a cat make you feel better. suppose you dont do burnout as well dont preach 2 me.

English?

amisupposed2b · 31-12-2006, 05:00 PM

Besides all the arguement, I must admit. Taking off you cat, may sound great. BUT it isn't a cool move to the environment, because if the environment suffers, we suffer, it may not even be your generation, but maybe you kids generation.

JoesAu · 31-12-2006, 05:28 PM

my cat is'nt off and it still has a bit of honeycomb in there. Bloody helll iwont say anything next time ive started world war 3 over a bloody cat convertor.

Without entering in too any debate or starting WW3 besides being against the law breaking EPA emissions etc are you possible doing any damage to your car at all by gutting your cat?

JoesAu · 31-12-2006, 05:57 PM

EXACTLY RITE. i know that many people who have gutted their cats rite out its nnot funny. by the way the car goees heaps better.

That has got to be the STUPIDEST argument I have ever heard. You are equating the change of a number of components to better performing ones as equal to removing what is probably the most environmentally significant piece of equipment on the car?
As a mechanic by trade you are obviously aware that, in most performance setups, cars are actually tuned to run leaner and burn more efficiently.. in essence that is effectively what an edit, unichip, chiptorqe, etc are designed to do, increase efficiency. The same applies to larger exhausts, bigger cams etc. They are all designed to use the avaliable fuel, air and spark to their most efficient means. That is the basis of any performance gain.

As for burnouts.. no, I personally don't do them on the street at all. However, in the big picture, the burning of small amounts of rubber (and yes, the fumes and smoke is noxious) on an irregular basis is absolutely nothing compared to a car running no cats for any extended period of time.

Now argue, preach, assert and whine all you like, you will find VERY FEW on this forum that would advocate the removal of cat converters from any car running ULP.
Its people like you that end up giving car modders a bad image.
