If you don't care about emissions then don't run one, save yourself the money for something else

Track or street use? Cops in some areas are stricter than others and tend to check that ----.

eBay has cheap high flows, just buy like a $30 one from there, weld up a flange on your dp and bolt right up. That way if you ever take the turbo off to resell, you can just bolt a cheap or stock header back up.
