How to build a top mount manifold with minimal warp

1. build your collector. i don't have any pics of building my collector, but space is sometimes an issue with top mounts so i decided to go with something a little more unconventional.
2. place your collector where you want it in relation to the head flange and start making your first runner. i decided to go with runner #3 since i knew it would be the most difficult to route.
3. tack it all together and then weld the runner, but not the pipe joining the runner to the head flange.





4. do the same for each of the remaining runners.





next runner:





5. once you have the runners all welded, bolt the head flange to a thick plate or head that isn't being used. i use a 2"x3" piece of steel that i drilled and tapped the head flange bolt pattern into to prevent warping.
6. weld the insides of the pipe to head flange seams to help prevent cracking.

you can see there is a little bit of warp, but not much.




the external wg will go on afterward.

you are a mook. mine is all stainless, pipe and flanges, and it looks like the same material that weirtech is using.


anyways, that's some nice footwork there weirech. looks good. why didn't you have the flanges CNC'd in stainless too?

what I did with mine after it was welded, is I had the flange milled flat again to remove the warpage.
