Message: <blockquote data-quote="Ratbit" data-source="post: 4167406" data-attributes="member: 88931">I have change the extractor for my campro engine just before CNY 2010, at first i intended to change to 4-2-1..but after finding out the "O2 sensor"(lambda sensor) for 4-2-1 extractor is located within only one of the hose outlet of the extractor,i opted to use back the "original campro extractor" which the sensor located at the end of the 4 outlet hose...after some discussion with the sifu mechanic..he explain that the O2 sensor actually important and it send signal to the car cpu of how well the combustion of fuel and air mixture in the engine, thus they help determine, in real time, if the air fuel ratio of a combustion engine is rich or lean , and manage the ratio of air and fuel being injected.. tempering and modifying the O2 signal that the oxygen sensor sends to the engine computer can be detrimental to emissions control and can even damage the vehicle.So after the explanation i used back the original campro extractor,after that the sifu remove the blocked CATCON and replace it with something like a large oval shape cylindrical connector,inside the connector have some swirling line markings,which the sifu said is to enhance the air flow, after that,the sifu change all my piping from 1.8 inch to 2 inch, i ask for larger piping but the sifu said cannot because of my campro engine capacity..afterwards he install a long center bullet with internal tornado / swirling lines..which he claims can enhance power !?after that he ask me to choose "S" muffler with double exhaust pipe...that is how my 4-1 exhaust system for campro is being born....after the installation immediately i can feel the acceleration become much smoother and faster to reach 100km..and the car feel lighter.At balik kampung time to penang for the first time my car can reach top speed like never before..!..what an adrenalin rush !"my wife sit beside me "bising" and said i wanna "tapau / bungkus" ....the fuel consumptions so far seems to be normal,for daily city driving,so far, i'm satisfied with the 4-1 exhaust modification....anyway sorry for the "cheong hei" panjang explaination..just wanna share my experience with u all..</blockquote>
