We should have something ready for 2014 cars about end of March or so. We ar doing all the CAD drawings now and will be able to make a prototype Mid march some time. We'll have one on a car doing testing with a cat too to see if we can maintain the no CEL that our 2012-2013 versions enjoyed.

Shoot me a PM with your production date and I can check compatibility. So far any F30/F32 made after 7/13 or later has had a different version primary cat.

Sweet. Yeah, the no CEL is a must for us MPPK/MPE owners who don't want to use a JB4 but still want the extra power and sound from a downpipe. If you could also do some dyno runs with just the HFC downpipe only that would be great.

We'll have to see if we can get a car with MPPK at a later date. The OEM ECU will be tested first. MPPK guys seem to be the few that have a CEL at times. It must have to do with a change in the ECU software for the o2 sensors.

We'll look at some other cats we can use as well to see what works.

Sounds good. I'll definitely keep checking back with this thread for updates. And if you guys are ever down in Alabama or you want me to send me a prototype you're free to use my car for testing! I have access to a dyno as well.

Thanks for the update. I have a 2014 with PPK/MPE as well, so I'll sit tight until what you have is ready (and CEL-free). I believe you mentioned before that you had a higher cell-count cat that you could also use that was more efficient (so still similar power gains) but would likely stem-off the occasional CELs... that would be the way I'd want to go.
