Ok finally made the decision to change my exhaust pipe... GPR Titanium!!!! Swee bo? Then went for inspection and paid another extra $52.50 for inspection... Then waited very long for the paper to be done cos singapore no one change GPR on bandit400 b4... Anyway the power respond only increase abit only =( But ok lar.. Still quite cheap... Hehehehe... Then have to thank God again this time cos during inspection the person said GPR only for class 2 bikes no record for 2A... Then they have to seek supervisor for advice... Then i prayed to God hope that can pass... Then lucky pass liao... Thank God for the new pipe, new wave disc, new cowling...
