Nice one ..I have R15 V3 BS4 model.. After market full system exhaust poturuken...But R15 V3 BS4 there is not a O2 sensor ..they launched only in BS6 version.. Enna questiona , I heard whenever u change a stock exhaust, Fuel mixture will get lean nu solraanga, and lean mixture is not good for the engine..unless I did a ECU remapping while change the exhaust.. So naa remapping alam ethum pannula apdiye verum exhaust maathi than oturen...ithanala any problem varuma engine ku on a long run..?? Because super bikesa alam exhaust maathuvaanga along with proper ECU remapping...so ECU remapping panna lean mixture avoid aagumaa?? Pls answer me on this bro..
