what's the different between 4-1 & 4-2-1 extractor?..my neo use the 4-1 extractor..it's kinda weak at the low end torque..

i dont know how to explain in details and technical words but 4-1 is indeed kinda weak at low end.. this is a racing setup that requires torque from mid to top end most of the time.. since CPS is not that strong below 4k rpm, it is not recommended to use 4-1 for daily use.. 4-2-1 will give u a balance gain to the whole RPM range

can i still used my whole piping system by changing the extractor only??

can i still used the same piping system by changing the exractor only?...and which 4-2-1 extractor is recommended?

 

[stuffx]

of course can.. but changing the whole thing is better

for extractor.. go for R3 4-2-1 extractor

Yes you can use ur current piping but i dont know it will be suitable or not.. There are alot of 4-2-1 extractor in the market... Diff ppl diff recommendation . . for me.. R3 extractor is the best~

I'm confused. I thought 4-1 was for low end and 4-2-1 was for mid to high? Since there's more backpressure with 4-1?

i'm currently using the hotbits piping system and the 4-1 extractor..can the r3 extractor be compatible with the piping system?
