bro, singapore got legal pipe gpr 650 wif inspection.. worth it?
Couple of my frenz using the GPR pipes for their sparkz.. It lookz wonderful on the bike,sounds perfectly loud and are street legal too but deres no performance even if you change the cdi or open up the silencer(it bcomz illegal).. Guess wat? Derez juz too many stopperz in the pipe,even more den our standard pipez.. Easy to say,u pay for the sound and lookz but not for the performance.. Well,itz ur choice.. To me,itz not worth it at all.. Cheers!
