Dedicated Exhaust Discussion

I'll rework the CAB heat shield while the headers and mid section are off for ceramic coating, it clears fine now but doesn't look very good.

Here's something I'm working on.... It's a 3-D printed stainless adapter that's "S54" on one side and "N52" on the other...

It has a slight amount of tilt-up for the header, like 1.5 degrees, so the runners clear the fatter N52 block.

Much less fabricating, I paid for $120 for both of them. I need to Tig these onto my headers and verify they don't warp or anything. More to follow...

Welding the header to the flanges was WAY easy. Just a no-filler pass of the torch to fuse the two barrels together at 80amps. The inner barrel is already fused to the pipe at the factory.

3D printed stainless is the least-fussy thing I've every touched. No warping, no drama; almost like it was designed that way!




where does the metal come from? I don't know, it's like magic...

Ok, this is crazy...

For LESS than the price of having these laser cut from SCS and less than just purchasing these off-the-shelf, I can have these 3D printed in stainless and also save 0.6lbs from a set of four....

$25 each from ProtoTi.com

(also, I'm not a huge fan of V-band clamps, at least here.)

That is just beautiful! Also that looks tight even with a treehouse style cab mount. I’m a little worried that I can’t fit stock cats in there😬

hoveringuy - Very cool, you wouldn't happen to be willing to share the CAD for those flanges? I'm gearing up for a swap into my e36 touring and that seems way more appealing than trying to splice the S54 pipes onto a stock flange.

This sub is great BTW, I've already learned a ton. I've been surprised/disappointed there aren't more resources for this engine in e36's.

yep, sent.

The plan is that once I get everything test-fit I'll have CAD for the manifold to head flanges and the two secondary pipes after the merge. You'll be able to fabricate a set of S54 headers that just drop into an E30.

I'm guessing probably not but suitable for RHD also?

Not necessarily. The cool thing about designing these in CAD is that "if you can imagine it, you can do it!". Not a stretch to model the steering shaft in CAD and then design the secondaries around it.
