5.75" S400 T6 Chassis Marmon Downpipe Flange W/Clamp

Very happy with purchase. Welded great, smooth just like their aluminum assemblies.
When no one else could come through BSI hits it out of the park.

The best down pipe flange on the market!

Very impressed with the quality of the flange, well machined and fits properly. The quick release clamp is also a handy touch!

I ordered two different flanges for my S400 from Black Sheep Industries and I have to say that these are by far the best quality flanges on the market! The stainless steel S400 compressor cover outlet to 3.5" tubing fits perfectly inside the cover and the recess for the tubing is spot on. The same goes for the turbine discharge flange to 4" tubing. I will be buying only from these guys from now on! Customer for life here.

Nice piece, smooth machining, nice and thick making it easy to weld
