QUOTE(shinjite @ Aug 17 2008, 10:46 AM) what have u done to your engine? Stock standard bro..But might converting to dohc/highcam later on If minimal mods, use 1.8", didn't sacrifice low end torque that much If your head has been PNPed couple up with fast road spec cams, use 2"   |

QUOTE(the_catacombs @ Aug 17 2008, 02:32 PM) maintain 1.8" lor if u need low end torque more, such as driving around town... if u high revving everyday, 2" will be nice... No la...Just normal cruising..Rarely touch 180 km/h  |

QUOTE(the_catacombs @ Jan 22 2009, 05:30 PM) this would be my recommendation for street use car... Agree..2 inch piping is max for 4g18pdrop-in k&n air filter tuned length 4-2-1 extractor midbullet replace ur catcon 1.8"~2" inlet s-flow muffler better still if u replace the piping with a little larger ones... this depends on ur budget... |
