[ART///SPEED]

1.8 inch will be sufficient.. make sure its not straight flow... use s-flow muffler....

u have to use s-flow exhaust. I'm driving lancer with 4G18 auto and change my piping to 1.8.

You will lose power if you use straight flow

 

[SkYwAlKeR]

yeap... if auto, try use s-flow muffler.... dont use straight flow piping.....

 

[wonderkid]

If you want to try straight-flow exhaust, maybe you can use the s-flow midbox or bullet. Not sure if tis will work... just my cents

 

[SkYwAlKeR]

bullet is straight flow...

sama geng, maybe. im using waja 4g18p. piping not to big, s flow and a tip of your choice, mandrel bent piping or something like that, a good bullet, like they said, 1.8 because you're driving an auto, 4-2-1 extractor, if you still intend using that engine. take it out, as your local mechanic to clean it and pnp. Im not really sure with the term cleaning it, could be "cuci" because they said mine was "kuat kotor". skim for increment in compression if you intend to go for N/A. Iridium spark plug, drop in air filter, motor oil, apex'i SAFC II, and cam pulley. So far thats what i did and the difference is alot. Much more smoother, and responsive.
