SLO247 1,713 Posted March 2, 2015 As above. Alloy head. I also have Tri Ys ( maybe pacemakers) and some Genie ones. Which should I use? Share this post Link to post Share on other sites
Thom 6,654 Posted March 3, 2015 They look the same as the cheapie no names I have on my xe 2 SLO247 and gerg reacted to this Share this post Link to post Share on other sites
gerg 10,871 Posted March 3, 2015 Genies are too thin in the wall on my experience. Those ones you show there are 6-2-1s, and without seeing the Pacies I'll assume they're the same. Pacies can be had in 6-3-1s as well, which are better. The ones in the pic seem to have decent radius bends (albeit press-bent) unlike others I've seen with really tight turns out of the end cylinders. Can't see the merge collectors very well but they they look like they're pipe-in-cone at the merge (good) but where the cone meets the secondary looks like a bit of a step. Could well be Hurricanes. 1 SLO247 reacted to this Share this post Link to post Share on other sites
gerg 10,871 Posted March 3, 2015 On a mild crossy, i reckon perfect. As long as they don't leak or aren't too rusty. Might want to think about swapping the starter for one with the solenoid 90 deg down and away from the pipes. The Bakelite cap on the solenoid cracks from the heat and then kaput. Later gear reduction ones are smaller too. 2 SLO247 and Thom reacted to this Share this post Link to post Share on other sites
SLO247 1,713 Posted March 3, 2015 OK thanks. I'll put a late Bosch one on it. Share this post Link to post Share on other sites
ando76 4,354 Posted March 3, 2015 I think that they will be fine - much better than a stock cast iron lump and better than some of the cheapies around. I'm not a fan of the pipe into cone on the secondaries on all these headers. Pacey's are pipe over cone and that is one of the reasons they work so well. On a mild engine they will be fine. If you want a bit more torque and better performing extractors then lengthen the secondaries making them 2 1/4" and pipe over cone and you will be on a winner. 1 SLO247 reacted to this Share this post Link to post Share on other sites
SLO247 1,713 Posted March 3, 2015 Good info thanks. As far as I know its stock so I'll leave them there for the time being. Share this post Link to post Share on other sites
