E36 M3 - LS3 New headers finished.. Your thoughts or comments would be appreciated.
Headers are custom built to fit the E36 M3 and are 1 7/8" primaries.
The rest of the system is twin 3" (Couldnt fit any bigger) through an X-pipe and a single large rear box custom made to fit and look fairly stock.

Looks good. If they allow you to fit the engine in the car then they are great 
I think 1 5/8" is a little on the small side, but it is tight in there.
That bell housing looks like it is upside down.

Edited, The primary size is 1 7/8 not 1 5/8!!
AX15 or Toyota R154, the same trans (The totota has more suitable ratios) Might not be up to holding the power long term but I have 3 on the shelf and replacements can be had here for about £200 - £300 each.

Very nice - did you fab them yourself?
A couple of things you might want to consider -
-Did you leak check them? I've made a seal for the head ports out of a flat board and a piece of rubber sheet from the hardware store and clamped it to the header with C clamps, then put an bicycle or motorcycle innertube on the collector end so I could pressurize it through the Schraeder valve and check with soapy water.
-I can't tell if the coating is paint or ceramic, but you might want to have them coated inside and out for thermal control if you haven't done so already
-Do you have your oxygen sensor bungs welded on?

Dude....those are sweet. Very clean and simple looking. I like the approach, especially how you positioned the collectors.... I'd like to have a set of those.
