Singh Posted August 5, 2006 Report Posted August 5, 2006 Will the headers from hum performance fit on the 3.4 dohc's ? http://www.humperformance.com/ Or am i missing somehting? Quote
ToroToro Posted August 5, 2006 Report Posted August 5, 2006 Yeah, you are missing the fact that your GTP has the 3.4 TDC, and those headers are for the 3800... Aint gonna work at all. You'll have to make like aaron and, well, make some. Hopefully you can do a better job though. Quote
Singh Posted August 5, 2006 Author Report Posted August 5, 2006 yea i figured that ahah that sucks, there should be more support for 3.1's and 3.4's too, show some love ! i guess i wont be saying that when/if i l67 swap heh Quote
luminal67 Posted August 6, 2006 Report Posted August 6, 2006 wow are there prices high compared to other headers on the market, those are cheap. on top of that, you will not need to modify your firewall. on a side note, a friend of mine testing out a set of those headers, has dropped half of a second off of his 1/4 mile times so far. that is not bad at all, going from ported manifolds to these headers on a mediocre tune.
