QUOTE(e30 @ Dec 6 2010, 06:37 PM) 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? Piping use 1.7". Follow original piping route. |

QUOTE(the_catacombs @ Dec 7 2010, 05:07 AM) If not mistaken about 1.5"-1.6"... 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. |

Crankpulley yes. But open pod not necessary better. Depending on ur driving characteristic. Drive slow low rev around town, stick wif drop in filter. If rev high and highway often, open pod suits u. |
