Remove Catalytic Converters

[gohkokeng]

hie dudes and guys here

people telling me that remove your "Catalytic Converters" can improve quite alot performance but got little air and sound pollutions.

Is this true? removing "Catalytic Converters" will against JPJ rules or not?

 

[awos_84]

cataltic converters (c.c) is using to burn the unnecessary gas which can lead to air poluttions. removing the c.c can lead to air and sound pollution because this thing also is used for absorb some sound..
the power u're expected from removing this thing is about 1-2% only ...
the outhority ?? of course against the rules cos u will make air pollute.

I dont know about the legality of it, but i can tell you it will give a mild increase in performance.

yah... saga got no CAT... only got midbox... jz change ur midbox to high flow midbullet....

 

[BLaCkHoWLiNG]

some say it helps with power.. some say not.. to me, all i would like to know is, would it help with the fuel consumption... coz was thinking of removing d cat conv. on my wife's car

 

[dorikin]

It would help by the smallest of margins. It would alleviate some backpressure so it would help. As for the making more power it does. A local magazine did a test on an r32 making 300ps. They switched from gtr cat to an aftermarket one and still got 15ps power gain. It would be even more with no cat. The more power the car makes the bigger the gain, as more back pressure would be gone.

will it give the car a sport exhaust sound?because i thought the muffler is the one that do the silencing?another question.removing the cc will it release black smoke?

 

[edwin_lcw]

midbullet i heard alot.......but duno how it looks like.....hahaha

how much 1 midbullet? does it come wit anybrand? does it come with variety of piping inches?

i am totally noob about it :~/

 

[theorekz]

I read an edition of RallyXS before on the evo8 MR FQ-340... RalliArt have an optional package which would allow the buyer to replace the CAT to a Jan Speed high-flow CAT which in return will boost another 10hp on wheels....

yeap... but this only applies when u changed ur headers as well...
last time after i changed into 4-2-1 headers without changing the midbox, my fuel consumption was terrible... within 1 week, i went back to the workshop and get the midbox replaced with highflow midbullet... now feels much better adi....

so, if u are still using standard extractor/headers, there isnt much difference by jz changing the midbox....
