Hi guys, while i'm happy with the stage 1 flash I've been really itching to do dp's but don't want catless if its possible. Anyone running these yet, if so whats your take on them?

LightWeight will sell soon HJS 200CELL catted downpipes for M2C:

https://lightweight-titanauspuffanla...mpetition.html

I have installed and used HJS downpipe for my n55 M2OG, n55 m235i Cabriolet, b58 X3 m40i. Perfect fitment, good sound, no smell. No check engine light for the first 2 year, but then CEL. I do not know, wheather the CEL related to downpipe usage or meanwhile the ECU software upgrade has more precise o2 sensor measurement.

I will order those for my M2C, once they will be ready.

Looks good, but if that I'm seeing that correctly that's 2999 euros?

Won't be cheap, that's for sure. Also hurts because you'll need 2 instead of 1 for the N55.

Does seems really high priced

[brad65ford]

Found these but they are listed for m3/m4, though I've read they will work, not sure yet. Let look good and half the cost.

Honestly not sure how well the ones I've posted are, but I'm all about performance yet wanting to clean up some of the smell without going full catless.

can't vouch cause I did AA mid before dps but maybe leaving stock secondary cats would satisfy your performance desire while cutting back on smell.
stock rear with AA mid and dps sounds so good (well as good as it's gonna get).
have my duramax 3/4ton deleted so I find catless gas way less obnoxious than catless diesel

[brad65ford]

Really want to leave the AA mid on, I think it made a huge difference in the sound. Much deeper which i like. Same I now need to find a catted down pipe to remove the smell. But I do follow you regarding catless down pipe with keeping stock mids would have allowed me to run stage 2. The one's I've posted I'm trying to research. Worried I will destroy them in a short time frame.

I concur on the AR's. I'll be installing these at the same time as I get my car tuned. Probably Ecutek, or BM3 once they get around the new software wall, BMW has on our M2C's
