    Does it matter if i get a Miltek Catback Exhaust or PowerFlow Custom exhaust then a bluefin? or the other way around.

    Nope it will not matter. I called up to ask this initially before i went for any software. Basically if you were to fit a turbo back exhaust then it would matter as you would need stage 2 software which would get rid of the engine management light for removing the cat or precat (something along those lines)

    However with a catback exhaust there wont be significant gains and the ECU will adapt to any slight changes the catback would offer.

    Im guessing with the bluefin you would be getting stage 1 software so it wouldnt matter which modification came first. I was interested in doing this once i had an intake but the people who write the map at bluefin said the ecu would self adjust to minor changes like an intake or catback exhaust (Even other bolt ons like a upgraded intercooler pipe etc)
