exhaust make over...

ok... after doing up my muffler and felt no improvement at all, i consulted some expert and non-expert about their opinions... they said i should remove this...



and replace with this...



after a few months, start rusting adi... huhuhu.... so i apply 2T oil (motorbike engine oil) on it to stop it from rusting... so far, the extractor still not punctured yet...



went home and found out my car fuel consumption increased drastically...
