Here are some prices things that I bought .. u can use the price as reference.. get the cheaper one

open pod KNN for RM250.. that was 2 years ago.. i supposed the price is cheaper

and i bought the heat block for my open pod for RM90..

i bought 4-2-1 hotbits for RM300 .. that was 1 year ago

262/252 mat speed camshaft for RM1300


i'm thinking to change muffler but afraid if the sound can be heard even from inside the car.. i dont want too noisy.. got small baby in my car any direct-flow muffler brand to recommend for quiet sound? i hope the quiet is last long.. not use for few months then get more n more noisy..
