Schedule 40 pipe
Anyone ever messed with that stuff? I was looking and saw you can get 90*, 45* bends and straight pipe pretty reasonable. A quick search says wall thickness of schedule 40 is usually .140" which is twice what most exhaust is. I was thinking that might be a better material to make a header with. Should be damn near like a cast log manifold and hold up for a long time. Would be heavy though. Seems like it would hold heat well too. Wadda ya think?
Oh.... And also I saw that 1 1/4" schedule 40 is actually right at 1 3/8" inner diameter. Just right for a small engine.

Re: Schedule 40 pipe
I've been trying to find some info on it. I've seen a few of the Honda guys use it on their short manifolds. Also noticed the 1 1/2" is 1.9" od which might work well since my new turbo flange is 1.92" opening. Would make an easy up pipe.

Re: Schedule 40 pipe
Happy new year to you!
I'm not sure what I want to use yet. I'm a bit concerned about the weight of schedule 40.
I love the look of yours! Not sure i could get them to make me one out of 1 3/8" pipe and the flanges I need. Plus I'm considering trying blow through. I've read several times people don't recommend it for some reason. I'm not sure why though, there are lots of blow through Holleys out there. If I go blow through I want to run the turbo low though. Just not so low I have to run a scavenge pump. So I just have to make up my mind. I suppose if I was smart I would just leave it as is until I go FI, but really if I build a new header it should cost me less than $150 in material.

Re: Schedule 40 pipe
Thought of schedule 10 instead?

Re: Schedule 40 pipe
I ordered mild steel mandrel bends instead. But schedule 10 would surely be a good choice. I think pipe would be a nice strong long lasting alternative to exhaust tube.
