Hi..
I'm driving a Latio 1.6.
Changed whole exhaust system from extractor til tip.
4-1 extractor, 2 bullet i guess, 1 s-flow muffler.
Previously on stock exhaust can hit 180kmh.
Now only around 150kmh. Something went wrong?
If change muffler to straight flow, will I get back high-end topspeed?

State your exhaust size.

Question, can I remove the catalytic converter but retaining the stock exhaust? This will need remap thingy cz to disable O2 sensor readings? No idea for exhaust

Yes, but it be more noisy.
If the car have downstream O2 sensor, either disable or use adapter/extender to trick the ecu.
