Once established, Aaron gets to work on the BMW header by collecting the raw materials he needs. From then he begins mocking up the piping and beginning the design of the header.

Speed Academy sent me here :D
The surfing part is amazing
This is great! Love the editing! 😎That mask wipe from the bench to the engine bay was slick. Those mask edits are always underappreciated. 😛
Keep it up guys!
2:20 had me fucking dying. XD
Nice job. So in the time it took to scan, render and compile all his (Speed Academy) data you have the primaries almost done.
SICK HATCH in the back!
That header looks amazing!
Awesome video Guys!! That header is pure art.
Looking great so far! Can't wait for the next Ep!
2nd episode will be up Friday!
Great soundtrack! Nice job
Awesome work guys
Much more entertaining than speed academys build lol
older BMW exhausts don't normally have flex joint because they don't need it.
Aaron is the man! #rhmt
This is awesome!
So how much fab time did it take to get the header to that point?
Based on the time codes off the camera for when we started filming and the time we stopped, there was around 4.5 hours in this header in this video alone. We took note of all the time Aaron took on the header and will be discussion it in a future episode
this is realy cool, insta thumbs up :D
Nice
How much does the firing order matter, When joing the primaries at the collector?
Crucial importance.
it was very important - we researched the design of the engine and looked at cutaways before Aaron started designing the header.
i always wanted to ask this retro style manifold is inly for 2 valve per cylinder engines or we can use them and on 4 valve per cylinder i have an m50b25 engine and i want to make something like this on it but i dont know if its worth it
Hello, how do you know the size of the tube to be able to fit on the oval?
Cool video :)
narrator has the personality of a rock
Don't worry, he's working on it!
He wasn't that bad. As whole the video was well done, informative, yet fun. Well done IMO.
theyre as bad as mine
Did I miss what material the tube was made from,, I am working on an inline 6 chevy
It was made from 304 Stainless, and you can find it all on our website
you choose the primary diameter by what fits in the flange? Wow, great tuning there guy . . .
That crx in front do
Alex Lachaine there is a whole series about that car too on this channel!
I'd be worried about the headers hitting the body when the engine twists
It was definitely something that was considered, Art got solid engine mounts to prevent that from happening
Lol so pitted
Did this child really call a Celica a Seleeca ? Yes he did. .
the mumbling is horrible
