My friend has suggested removing the catalytic converter of my vitz 2010. According to him the Cat conerter is for foriegn grade fuels and in pakistan it does not function well due to bad quality of fuel. Once the catalytic converter stops working properly my engine will start knocking then it will be too late to remove the converter......
is my friend right ? :s should i be removing the catalytic converter when everything seems to be running well for now?
i own city manuel 06 having the pick and consumption issuue done everything like tuning throttle each n everything after i feel lil change in pick and car gets lil responsive and fuel consumption gets almost double but the thing is even after using the hi octane from recommended pumps however its acceleration isnt that responsive no cng installed btw..
i've heard about cat converter things should i get it changed or removed..??
