I was just wondering which of the two mods would give me more GO,
either extractors ( pacemaker 4490) to go with my exhaust or the Powerbond 20% under drive pulley with idler pulleys?

Cheers.

Save and do both then a tune for the best gains.

If you must pick one, it would be the underdrive pulley for me.

If you want more 'go' then either get hotter cams, or lower diff gear ratios IE from 3.46 to like 3.9 or 4.11 (you will need a tune for both options). Cams would give power, the diff gears would make you get off the line faster.

Seeing as u already have most of ur exhaust , finish with 4490's .
But I reckon the underdrive gave more GO..
Proven 8-9 rwkw.
