Some hardware upgrade

The modification bug bite a couple of months ago and there is a pressing need to scratch it.
So scratch it I will.

This modification involved killing the cat.
Yes. Cat.

I killed the cat here.
Of course I've pre-order my downpipe a few weeks before hand.
I highly recommend Jian Hang due to Ah Wa superb workmanship.

This is how the original factory catalytic converter looks like.

How the engine looks like with the factory catalytic converter removed.

I junked this restrictive factory catalytic converter into a custom after-market downpipe.

A comparison of the factory catalytic converter and the aftermarket downpipe.

Now what is the difference after swapping to an aftermarket less restrictive downpipe?

Frankly speaking, you won't feel any difference but this step is required if you are to enjoy the full potential of the software portion.

Hehe.

Stay tuned.
