Yep I just did it before you posted. I thought when i saw it move 5mm the bolt was not effecting it but yeah now I have it out yep still dont quite get how it was able to move at all with that in there but anyway. Shows how many bmw columns iv removed. My mercedes is a dream compared to this of course its later model.... thats my excuse for my dimwittedness anyway. I ended up with the headers lying all over it and the steering in the wrong orientation to remove the bolt.... just me making my life difficult.... LOL Anyway now I can hopefully make some progress!

Those that have undone the columns in these e34 bmw's does this sliding shaft slide up inside the column shaft if you just loosen the big nut and obviously the universal clasps at the other end? Im having trouble moving this shaft up out of the universal clasp underneath the car where it connects into the steering box... This is the only thing stopping me from removing the drivers side headers as it appears they cant be removed without moving this column shaft out of the way. Im building probably two sets of e34 headers for Richard and Ian. Just getting started on it now. The nut is loose the universal clasp nuts a re loose and it moved up about 5mm in universal spline and doesnt want to go anymore. Looking at the spline in the passenger compartment it looks like that shaft can go quite a ways up into the column tube?

This is the video I was telling you about Richard. And is the reason I decided not to fit X pipes to my own E55 headers. They work at low speeds to mix the gases/sound but at high speed they do next to zero (maybe some scavenging but you wont notice the difference on a dyno imo). As you can see if you watch the leading edge of the exhaust pulse gas it likes to follow what I would call the inside edge or short radius bend of the tubes. This is also why I do not tend to make what I would call a parallel centre to parallel entry/exit design X pipe and like Richards I prefer the Splayed centre to parrallel entry exit design as it forces the gases to mix more. This is all from my own experience doing this on old restomod chev and ford v8's. If your after outright flow out of an x pipe the parallel centre to parallel entry/exit x pipe is the best bet if you want an x pipe. H pipes I wouldnt even bother with but thats just me. Of course I will fabricate whatever the customer wants. I prefer just twin straight through totally separate exhausts on v8's. My ears like that the best. Its all a matter of opinion and everyone has a different one on how they want their car to sound. Obviously street cars are a different scenario to race cars. I have never really seen anyone make any real hp from a x pipe or h pipe or Y pipe its all 1-5hp or nothing the scavenging effect that far down the line is usually not a massive factor imo. If it was me I would be semi gutting the rear mufflers now. But I agree with michael on what he says about the duals.

Hi guys im the one making these headers (Stirling Steet Machines FB). Obviously these are built to a price point being steel and what goes with that (I have spent way more time on these than what I have charged Richard, jigging up etc)... As mentioned above something like the jedders unicorn headers can be done aswell but someone would have to pony up a significant amount of money (and an e39 m5 or similar) to get it done. The Jedders unicorns appear to retail around 8knzd. I think I could make copies of those for around or just under 5k just to give you guys an idea of what it costs to do headers of that quality. Just depends on how tight a raidius most of the bends have to be and all that. Anyway I dont know whats allowed on here as far as business advertising (im just a guy working out of his shed at home BTW) so I'll leave it at that and someone can let me know. If anyone has any questions let me know via pm. Pictured my E55 AMG set I have on my own car. Will most likely start on m156 E63 amg set next.
