dont waste ur money to mod exhaust or what. wira 1.6 with stock condition should achieve around 190km/h or at least 180km/h even in stock condition. go and service ur car and make sure ur engine in tip top condition. check ur clutch plate for any slipage. what rim size u r using now? the diferrent between 1.5 and 1.6 gearbox not very much. only at the 1st and 5th ratio. my 12years old putra still in stock condition and still can achieve 210km/h with no problem. run on 15inch rim.
