Hello. I know this is a late reply. I have the Duncan pipe on my Raptor. If I had to do it all over again, though, I would go with another brand (Sparks, Lte, etc). I have had issues with the Vortex EFI unit and Duncan does not want to admit it. I have now switched to the PC III, which except for not being waterproof, is a superior unit. my 2 cents.
