Hey Zookers... So things progressing with the project and engine finally going in this weekend. I'm planning a new exhaust and have been eyeing off some of the sexy looking extractors on EvilBay. However the stock headers on the 16B almost already look like extractors not like the constricted headers on the 16A. My question is - is it worth the upgrade? All feedback appreciated as always.

The g16b manifolds are prone to cracking and those fat looking down pipes are in fact double wall and have a crimped pipe inside them. Check my build thread- the guts of my downpipes were broken and rattling about. |

Extractors it is then  Not gonna stuff around with the old headers and much easier and cheaper to put on now with new exhaust than later

4 into 1 are the only ones worth doing powerwise most ebay 4-2-1 are junk I run a jimny g13bb manifold on my g16b and would wager it makes as much or more hp than 90% of ebay extractors |

I've ordered a set of 4-2-1. Let you know what they're like when they arrive and how they go once installed |
