punching out a cat achieves NOTHING as well.

apart from making ur car sound louder :P

didnt even do that

in jazz high flow cat makes some differences...

Hemm.. changing the exhaust should not effect much on the accelleration whats so ever. Unless you get the entire new exhaust system. Which I believe Zimp have it.

However since you lost power! it only mean the exhaust installed is not for your car. Getting rid the CC will make it worst.

The only best thing to do is to replace the current exhaust with the one made for Honda JAZZ. or just get the entire system (header, downpipe, bpipe, and exhaust)

shouldnt buy the cheap canons in the first place bruh!

i got cheap cannon off these forums for my jazz and it definately made it more responsive in the higher end of the rev range and improved fuel economy. Everything in the jazz seems to be restrictive.

Brought to the guy who fitted my muffler and he said that it's just strange for power loss. When i asked him about changing high flow cat, he said its not a good idea...will lose more power.

So i brought to a mechanic i know who focused on jap cars modification. He said exactly the same thing as u. Pipe is too big, lost back presure. He advised me to fit a VAFC or change the muffler. Recommended spoon,mugen or hks.
1) spoon has reasonable price, but only n1 style for jazz
2) mugen is a little too expensive
3) hks - few styles and price ranges between spoon and mugen.

I have to wait a little longer to get new mufflers from home, now have to stick with the current one for a bit. Parts in australia are too expensive.

whats the diff between high end and low end??

thanks for the info

Which type of intake do u guys think is better??

pod filters or just replace the standard one??

Without any changes in the exhaust, you should go with standard K&N filter or simota..Open pod will decrease your performance..
