Taa. Must be some valid reason why the rear pipe was formed that way. Whatever, looks like a big obstruction.

looks like they shaped it using the same machine that shaped the front control arms

Other than clearance on LHD, may be timing?

good point.. timing as in when the two turbo merges, there may be some resonance tuning going on

Good point. I was wondering the same thing. Not room enough to make the two outlets the same length, like with a good set of tuned/equal length extractors, so they do this? The proof with power will be on the dyno & the 1/4. Not sure if there's any other issue they're trying to negate like back pulses feeding back to the turbine wheel(s).

Gazz saw a 1M apart, and confirmed that the crimped pipe is due to clearance issue of the RHD.

Correct, Its called crash clearance so if the car is involved in a crash the engine can move on its mounts etc causing damage to other components. But the clearance is excessive and not needed.

Ignore all the speculative bullshit below then...

So in standard form our RHD N54s are likely to make less power than a LHD car, particularly the rear three cylinders?
Would solid or less flexible engine/gearbox mounts be a good fit with this mod?

By what I saw on the 1M motor out of the car there is enough clearance around the section of the steering column where the pipe is crimped to fit a standard, i.e. non-crimped, pipe. I can't say what effect that would have in the event of a smash. It may limit the deformability of the steering column which could mean that you would be shish kebabed and have a reverse BMW imprint on your inards. But then again maybe not.

If there is no change in the speed and volume of gas flowing through this section then it doesn't matter what shape it is.

In any case, the car I saw being prepped for racing will have a non crimped pipe fitted.

old thread but lucky i found it. I searched quite a bit, gave up, photographed my dodgy outlet pipe, was just about to post and ask, then i found this thread!

it is good to know that it is as per design, but hard to believe it wouldn't have some affect on performance at some point. my question: does anyone have a before and after dyno mod example of this yet? (that didnt also have a ton of other mods done at the same time).

Why cant that section just be cut off and some silicon pipe used to fill the gap? That seems the easiest and would negate the supposed crash effect of welding in the sections as shown

Because it passes within millimeters of the exhaust manifold feeding the rear turbo. Silicone wouldn't be a reliable solution.

Silicone is the material being used for some of the complete replacement pipes in development.

What kind of temperature tolerance would it have to have to pass mm from an exhaust manifold at 900+ degrees C and hold up long term? Silicone hose burst pressure is typically halved at it max temp resistance point. You've got internal heating from the turbo charge air temp and external heating from the exhaust manifold(s) - I'd much prefer ceramic costed metal piping, especially over the long run.
