Finally, I finished my exhaust header. Don't laugh at me too hard, it's my own design, and I worked with the tight space I had under the bug.
I't all stainless, with equal length primaries, and merged according to the firing order.
The muffler is from some motorcycle (yamaha R1 I think).
Welded the bungs and soon I'll have a wideband O2 system and EGT reading
Drove it a few km's tonight and as far as I can tell, my bug has never been so silent before, which I like very much lately.
Better pics coming soon.
