The e28 headers are fine, the front downpipe also works, however the back downpipe had to be slightly bent down in order to have sufficient clearance from the firewall. Without bending it, it was touching the firewall which is a safety hazard with the heat, with it now bent it has about 3/4" clearance.
I have an e30 M3 EVO airbox with a new filter all painted and sitting in storage, I just need to wait for the right time to install it. I leave for college on Tuesday so now isn't exactly an ideal time.

Well, bugger me. You got it done.
How did the e28 manifolds work out? Does the back one interfere with the firewall?
Also, will the M3 airbox fit in there? Looks like the AFM is pretty close to the front of the bay already...Leave a comment:

Well, before I store it up for the school year as I go away to college, I'm taking one last photoshoot for all to see. Things awaiting installation are Bilsteins and an M3 Airbox as well as cleaning up a bit more wiring. A little bit of info on the motor:
•e28 headers/downpipes mating up to an e30 m3 center section and muffler
•custom Alpina intake manifold with relocated throttle body
•custom notched subframe re-inforced with sway bar tabs and motor mount tabs from AKG motorsport
•Engine position "3" with 324td fan and fan clutch (thinnest fan BMW makes)
•Custom "hartge inspired" motor mount brackets
•Ireland Engineering Motor mounts
•New 535i clutch kit with resurfaced flywheel
•Custom made, newly rebuilt driveshaft
•Custom throttle linkage assembly with new bowden cable and extended throttle plate/pedal
•many more maintenance items replaced with too long of a list to spell out
Engine warms up to correct temperature and has never overheated and even come close, the mechanical fan does it's job very well.
Feel free to ask any questions
