My Myvi Gen2 model had always facing issue on hard to rev up, especially during up hill, is like dragging a cow on the mountains...

I had since suspect something to do with my AT gearbox, but even a visit to Perodua said that my gearbox is fine, but then they didn't explained to me why the hard to rev up...

So though my friend recommendation, I went to a bengkel to check again, and the bengkel said that is could be due to CAT blockage and advised me to change...

Due to I being a noob and just said that I had budget constraint, they just recommend me a sparepart and promise could solve the hard to rev up prob with reasonable price and I just okay with it.

Then when all finished and I started to smell something not so nice, then only I realize that they remove the CAT totally and replace with something like catless extractor...

Due to everything already pasang and what not, I had no choice but to go with it...

So question, what are the pros and cons on not having CAT and go for catless extractor?

Is it possible to place CAT back in the future? Will it be very expensive?

Can but just get kedai potong kete. Cat is mahal cos ada platinum kat dalam. Unshoild ask the shop back fur cat and keep at home. Just that will have faster global warning thanks to u. (0.00001% quicker)

Just decat.

More power but higher FC.

Thanks on the reply, may I know why I should keep the CAT?

Actually that fella also got said can tried to cleanup the CAT, but he no recommend that...
