Take out cat converters?
#2
In GS430 I had 3:
- 1 on each pipe before Y
- and third one, bigger after Y
I removed all, put "emulator" before lambda and it works without problems, no check engine light.
Is it lauder?
yes, but no so big sdifference
I do not see any performance/acceleration improvement and less fuel consumption.
You can check my Thread for details and sound.
