No mention for CP-E? They are cast and probably have the best wall thickness, fitment and great flow right off the turbine.

VSFR - cheapest set at ~$385. However some people have complained about their raspiness. I suspect from thinner wall thickness.

Performance wise, all of these options do the same thing.
Our wall thickness is the same as AR's & MS's

The rasp is from being catless.
