AA midpipes have shown HP increase per their dyno charts.

The biggest advantage of the midpipes is the sound upgrade.

Their single midpipe eliminates the S55 raspiness for a clean deep tone without the metallic sound on high RPM.

The equal length midpipe transforms the sound to almost a naturally aspirated engine with a balance sound increase.

Thanks for the info Mike.
I have two more questions.
Does this full cat-back exhaust pass New York emissions inspection?
Also which catted downpipe is best to pair with this system and will catted downpipe throw SEL light and pass/fail NY inspection?

I cannot comment on emission as i do not know the laws of your state.

Single midpipe or resonated EQ + REMUS axle-back + catted downpipes sound great. Its 2 different sounds, i keep going back and forth on which one is the best

Hey what's measurements on the tips, do we know?

Datka,

1st off the AA Catback should not be an issue if you leave your downpipe cats alone.

The system does get rid of the secondary cats but they aren't monitored by any O2 sensors.

I run the single AA midpipe with the Wagner 200 Cel HFC's. I needed to add some mini Cat O2 spacers to pass the OBD11 Readiness check here in MA.

I'm not worried about it passing an actual sniffer test. I had an EVO 10 with a HFC on it and it also passed the sniffer with a 200 cel cat several yrs back.

My advice is NOT to go cheap on HFC's. The good ones are going to run you right around $2K.

If your not tracking your car or planning on tuning it I don't think HFC's are the best way to drop coin on your M2. If you do the above then I think its a worthwhile investment.

HFC's will increase your exhaust sound around 20-25% both closed and open valved.

HTH,
Steve

Thanks. This is the answer I was looking for. I track my cars and not looking to make my car much louder, but rather need lighter free flowing exhaust that reduces the back pressure significantly without tuning.
I tuned my 135i and then 340i and will not go that route again as it compromised engine reliability(without supporting mods of course) on the track when pushed to the limit.
Don't have M2 yet, but new M2 comp. will replace my 340i soon.

You will not have any problems with the S55 trackside. The cooling system is wicked good. I've talked with lots of S55 track junkies regarding this.

This was my #1 reason for waiting till the M2C came out for sale.

I'm running a custom Pump 93 tune which is probably around 510-520 WHP.

I've got both the AK Motion Display & Elec M Sport wheel showing coolant and oil temps. I couldn't believe that neither moved during multiple 20 minute track sessions...

Its one hell of a great track motor

[Datka]

Thanks. Just looked at your M2 c build. Wow, the list of your mods is impressive.
Would be interesting to see you in that car at the track.
Which tracks do you go to in the north east?

[wavyyyy]

I'd be down for an NE track meet up, it would be my first track day though lol

I haven't gotten down to LRP for a few years now. I spend most of my instructor days at Thompson, Palmer, NHMS and Tamworth. Also Tremblant.

I'll be at the BMW opening event 4/24 at NHMS this year for sure...

Stick your hand out if you show up!

Hi,
Please send all order update questions by direct DM, not on public threads.
I also will need your order number to get an accurate ETA from active

Removed. Will send DM.

This gets delivered Monday for me and will be going on with the EL Midpipe right away. I'll get some vids up.

Will get tomorrow. First impressions, bad in efficient but really good otherwise. Efficient is raspy.

It really wakes up around 5k.
