if you're not particular about noise and good hp gain, practically you can go to any exhaust shop. i think whole setup may cost you about RM 400 to 500. As compared to famous exhaust shops that may cost you RM500 just for a header.
will organise a group driving MR car together go to JOM PANDU , will start dive on afternoon from JB to KL , may stop at any Rest station if somebody need to join us
beside MR car also can join us...
