so does it move under it's own power?
I asked him that today, he said that he pushed it fast and made the mazda "zoom, zoom, zoom" noise, and that was close enough.
can't sleep, so I ordered exhaust parts. I think the kia manifold just won't cut it

now I just need some stuff to go in the middle. 1.375 tubing. Anyone know the cheapest place to get mandrel u bends? not as many 90's as in the gay ass model, but center dump style like that
u should put your inside 2 cylinders to the outside of the collector and your lenths would be closer
I agree, that design sucked
it'll probably be more like this, but I have to wait until I can take some measurements from the car again. I might switch the 3 to go over the 4 to make it longer, maybe do the same to #2. its pointless without measurements though.
Where do you buy your prebent mandrel pieces?
and how the hell do you weld the star in between the tubes? pull the gas line and purge it over the area with 4" of tungsten sticking out?
I think the star is welded in before welding the tubes in the collector.
that way doesn't sound any easier. at least 1 tube is going to be a mother****er to weld
maybe tri-y is passe but why do you want to do a 4-1 dump? Seems like it would be the ticket for the revs this thing will probably do and easier to weld too. Speaking of which are you talking about trying to weld only from the outside? I figured the collector would be welded from the inside with a pen-style torch.
I found some website where they did a dyno shootout on tri-y and 4:1 with different lengths on a miata and the 4:1 was more better
I'm also fighting steering arm clearances with the exhaust so my options are pretty limited, the stock manifold works if you never have to turn left.
as cool as it would be to build your own header, how hard would it be to convert to rack and pinion steering? And I think espearo has bought pre-mandrel bent joints before, maybe ask him where? Trick-tools' most recent email showcased some sweet header jigs
Other than drivetrain, I'm not changing the way the car handles. I want it to drive like an Alpine.
Weld it from the bottom:Quote:

Then weld your collector.
I thought the tubing extended past the star in most apps. guess it doesn't matter
