I have today received my long awaited FMF Apex from US. Have it already fitted it to my beloved '08 CBR 1000RR... The bike now sounds deep and throaty from idling and evil and serious at anything past 6000rpm ... I also like the CF finish. However the midpipe does NOT come with socket for the lambda sensor like the original OEM pipe?! I ran the bike without Lambda Sensor for a small test run and no check engine fault came on but I fear that it will run rich (create additional problems?). The ECU will have one less input as it stands.. I thought of drilling the midpipe, buying a metric SS nut and welding it onto it to fit the sensor. What do you think?! Please do let me know your thoughts. Thanks!
