Hi Kweng

With almost everybody changing the extractor and piping have anybody encountered problem with the engine? especially when there is 2 sensor's?

one at the exhaust manifold and the other right after the cat converter ? Coz I tried that on my chevy and now I have check engine light on red all the time becuase i removed my cat.

Now I looking the thought of doing it to my 1.5 myvi and the same 2 sensors are seen on the stock exhaust.


thanks and kind regards

ok finally done my rear sflow box for my MYVI 1.5 and yes I do feel the mid to top now, thanks and still not happy !! ke ke ke I think I am expecting too much from a 1.5 engine!

Eh Weng now can I try the 421?

But thanks to weng and kakiexhaust for a good job and extremely reasonable price.
