hope this is the place to ask.. i'm looking for my first performance mod on my 4g13 satria (manual, injection).. guessing i should start with exhaust and intake.. should i go for open pod or drop in?

and how much is the powerzone 4-2-1 extractor for 4g13/5?

hi, my car is a satria 1.3 injection. currently i'm using a 4-2-1 extractor (cap ayam) and replaced catcon with a straight flow centre bullet. everything else is stock. i am planning to change my muffler to a straight flow (2" inlet) , but am not sure what piping size to use from bullet to muffler? is the standard piping ok or should i use larger piping. oh ya i plan to follow original piping route and not straight piping. any advise?

thanks for the recommendation. do you happen to know what size the standard satria 1.3 piping is?

oh ok thanks. from what i heard, the satria/wira SE uses 1/7" piping. so perhaps i will find a used piece, or just get one made at the shop.
