Persona's new header.

[fatality69]

I just got myself a chicken brand 4-2-1 header for my ride. Plus Top Cat midbox too.

Result was really nice. Much smoother power delivery and better torque.

Just wondering though, what is Campro IAFM engine's firing order? I was told this version i was recommended is far better and its a newer design that the older ones. Whereby the new version is primary 1 & 2 connected to secondary and primary 3 & 4 connected to the secondary.

Pics below.

So.... i was told this is the best setting since when both cylinders are firing, it does not clash against each other at the secondary pipe inlets.

erm... i had a few nicks in zth due to registration problems which went unsolved for quite a long time. dunno why. so i end up with this nick....

rpm range..... it feels lighter almost across the rpm band and most notable around 2.5 to 3.5k rpm. have yet to have it dynoed to show before and after though.

I got the before dyno results.

Hmmm.. Seems like there is no ideal perfect correct set-up, but as long as the gas exhaust does not clash at the collector then its ok lah.. Cos the 1-2,3-4 sequence also the gas flow alternates between the 2 collectors as the firing sequence is 1,3,4,2, so shdnt be a prob.

same like me..i before that i use hotbit extraxtor (1,3-2,4)...nd then change to h-performance superstert (1,2-3,4)..it was not very appropriate setting from 1.2 -3.4, especially when climbing hills .. .. very slow ..
