I agree that I'd rather go the SS route versus what somebody fabbed themselves in a garage or had built in China, lol.

What about streetability? I move around a lot (military) and am likely to spend at least some time in CA, so I worry about being able to pass smog, etc. And I want decibels to be reasonable as well (i.e., not dedicated track-car loud). Any thoughts?
I suspect the headers will be where the power is. But, we'll see.
