4-2-1 Extractor for pickup or top speed?

[phantomCL7R]

Hi Yong,


That what i thought at first, have you actually tried 4-1 yet? The thing is, all this time many friend have told me that 4-2-1 is good for city driving because of its low end power that it gives, and 4-1 were meant for track use because most of the power only happens at the top, but the funny thing is, when i was using the hot bits 4-2-1 system, is feel my power band was at 4k onwards all the way to redline, pulls strongly at around 5.5k, so i decided to be adventurous and go for 4-1, to my surprise the power was instant from low end, and it ended early too, perhap after 6k there wasn't much pull, by the way i'm driving a G2,

i agree with u bro..although u're not driving a gen2 anymore hehe

hello, i use a gen2 1.6 4-2-1 extractor, 2 inch piping, a centre bullet and a were wolf 2.3 inch exhaust.it really give an improvent when striking 4k- 7k rpm.. :)

i use 4-2-1 (pipe 1,2-3,4) from H performance for my satria neo..but, power is only when the horizontal way... when climbing a hill, my car lost a lot of power and be a very slow when climbing hills...

Really??i wonder...perhaps your air intake is insuffficient, are you using stock air filter or high performance drop in air filter or open pod air filter??
