Most makers of DPs seem to only offer catless since that's what most want since they're cheaper and give the most performance. The HFC is a great option for those (like myself) who are worried about the smell and hope for no codes thrown, but a lot probably have a tune also (JB4) that can auto delete. The issue comes in when you want to pass strict emissions tests.

Guess we can't have it all... $800-$900 for a DP that isn't much of an improvement over stock would be a tough sell IMO. But if it offers the same performance of a catless, then hey, I'd probably grab one if it can pass emissions tests and no chance of throwing a code.
The higher cell count cat we can use is just as efficient as the 200 cell one, just the cost is much higher. Some guys barely want to spend $650 for the HFC one now, so putting it at $900 makes it even a harder sell. We'll mess around with it some when the schedule opens up some more, but I just don't see as many people lining up for a $900 option
I just spent $800 on a 400 cell DP for my wife's Acura RDX...

If you build it, idiots like me will come.

We have it on the radar, but have to finish a few exhaust projects ahead of it yet.

I'll ask our BMW advisor next door, see if he can confirm the code status. usually the only ones that stay on an active are safety related like SRS/airbag codes etc. from my experiences.
Any update on whether clearing cel codes removes them entirely?

So far the downpipe has fit all F3X series cars including the M135 in Europe.

@GTM_Challenge, I've read that the turbo flange/mounting brackets are slightly different on 2014 models... will you be releasing a revised HFC DP to fit the new 2014s?

Fitment testing on my car begins next Friday. BMW made a lot of small changes all over the engine bay, Challenge already knows what needs to be done .
Chargepipes don't fit the MY14 charge pipes either :'(

No Evolution Racewerks confirmed it doesn't fit MY14 xdrives. They can't get a car to figure it out though.

mppk changes the sport gauges is why I'm assuming. I forget how how high they go but I do know it's increased over the standard. Looking at this pic makes me think they show 400 with the mppk software.

Correct - I've got the MPPK. If the earlier guy looked at the top of my post, I laid out exactly what I have.... It's also in my sig.
