Errr... actually is my gf's bro in law, he is back from US and he often join drag racing there, so this is the recomendation from him to me on my prelude.
ANyway, i am gonna change the muffle also, coz kinda sound too loud from the previous owner.
Actually the price is around RM700~RM800 as he try it for his previous 5th Gen Prelude in Wei Yip.
I want to change it before installing the Apexi VAFC I in SUnway tomorrow.
