i hope its not the open mouthed pipe .. its proper exhaust..
so if it is a an exhaust . then my expiernce says no negative affect on bike life.
infact my bike petrol and pick improved after i swaped dhoom silencer with qingqi vendor one .. sound is increased . so is pick and speed.
same is the case with pod filters ,, i have bored my dhoom to 50 piston of qingi and using qingqi carb with pod filter and petrol avg is b/w 50- 58 if speed is kept below 60kmphr.
