2300+ sounds expensive, and it is, but it isn't completely out in space... break it down & compare against some other headers:

1. Stainless always adds some coin, esp if you have priced good 304/306 lately.
2. If those are REAL merge collectors (which I'm sure they are), not just pieces that look like them, that adds a good 4-500 retail. Don't believe me? contact SPD or Burns Stainless.
3. The V-band (Marmon) clamps & flanges aren't cheap, either.

OK- that may not sound like $2300+ worth of justification, but you gotta pay to play.
