so im thinking about making an exhaust manifold for my civic... and since highrisers are so sweet... im thinking that would be oftly cool to make... so i rhinoed up a couple ideas just a few minutes ago, and here is how it turned out... kind of a rough quick job

BTW, the hight wouldnt be that extreme... though i would go for as high as i can go... might even have to wrap it with heat wrap so i dont mess up my hood...

rofl htey look awesome man, how would u make it, or would u just print that out and give it to a metal working shop. hey question, since the headers have to be able to withstand extremem temperateurs what are they made out of, does the material made out of determine preformance?

im going to make it in my shop class... and i was planning on using stainless steel... stainless can handle some pretty intense heat...

Well, your idea as good as it is, could pose a problem. Aftermarket header companies use dyno's and trial and error to get the most horsepower for each application. If you make your own header, you are taking the risk of having the car make less horsepower that it did with the stock manifold. Unless your going to research the header topic to find out what size tubing to use, what bends make the most efficient path for the exhaust flow and other co-efficients, then save yourself the time and buy one ! You might assemble a head-ache instead of a cool head-er.. :2cents:

a high rise header? I heard of a high rise intake manifold, but how would the rise help the header?? Shouldnt it have more restriction cuz of all the turning and the headers going up

That is what I thought too... It looks cool though M6M! :thumbs:

I think they look pretty cool too. But what sort of shop class are we talking about? Is this like grade 12 auto shop or metal shop?

Just seems like a hard job to do, especially during school time.

Screw the money spent on headers and buy a turbo!!! It's by the far cooler than headers.

well, there are some cases, that ive heard, where sometimes air travels faster in cases like the highrise header... now im not saying it will in mine... but itle look better than my stock header, and will be overall better than my stock manifold

like, i guess it raises exhaust velocity, and gives more torque...

heres a few pics that i found to demonstrate my idea...


or this compact design id like to try this too, but it would be like, super hard

Hey, wether it works or not it will still look pretty cool! :thumbs:
