after alot of debate about this in the past the best bang for buck 4-2-1 seems to be X-force.

the best 4-2-1 with plenty to $pend is toda.

however, there are many different opinions out there..

hey.

I've got some RS*Rs 4-2-1s on my CRX - i can't tell you dyno power difference as I haven't done a before and after comparison but I can tell you that down 400m my top speed improved from 138km/h to 145km/h - so yeah - they are improving something - and mine cost $700 second hand few years ago.

how much are those headers bro?

Just something you may want to consider. The NA small 4 cylinder really struggles alot for torque. The header is the best and cheapest place to increase this without opening the engine up, so it might be wise to spend here where it really matters.

Just one mans humble opinion

best bang for buck imo is xforce, but anything is better than MOST stock honda exhaust manifolds.

best header definately for d-series engines in auz.

**locote** · 19-08-2005 06:35 PM

any one heard or Hytech i saw some dyno test on a B16a and power went from stock manifold 138hp to 189hp with the hytech header its unbeliveble!!!! they cost round 1350 US dollars but
