I have been working on my 89 M3 Restoration and S54 Swap for 3 years now and Tyler @ The Arc Asylum has been a wonderful guide so far. I first bought his Custom Front Subframe and S54 oilpan along with the 6 speed trans brace. Seeing the top notch of his products I knew he was a great fabricator. A while back he contacted me and asked if I wanted to be the very first person to run his custom headers for the S54 swap and full exhaust, I jumped on that very second and that road came to an end this morning when fedex delivered a 65 lb box at my door. I can not stress how impressed I am with every part and the hours of work that it took to complete. Bolted up the headers for a quick test fit and they fit like a glove. Here are some pics I took today when I unboxed the system.
