Mid pipe power gain??

[AlteredBe4st]

Does mid pipes make a noticeable difference on the FX?? Been thinking about adding a set to my car but don't want to waist money on low gains. If so what are the increase in power and where does it make more power low end, mid range or high end. I am currently running AA down pipes, ESS tune, Drop in filters and would love to feel more top end power, I'm coming from a ESS Supercharged 625 E90 and miss the top end power, right now the M4 seems like it dies out on top end. Thanks in advance.

More for sound upgrading as you won't really get much performance gains from these kinds of mods. If you already got the downpipes, intakes, tuning, etc, the only real performance bang for your buck is upgraded turbos.

Might as well get the mid pipes so that the car will sound as good as it is fast.

What kind of speeds are you running where you feel there is not enough power?

Most manufacturers are claiming 15-20 Hp. Im looking at purchasing a set too, but mainly for sound than HP. There is a lot of info on the forums. There are arguments on weather they increase power or not but I can't say from experience. Some people say yes they felt a difference, others say no and that the stock catted DPs are sufficient enough. Looks like there are a lot of people running them though.

For the sound alone it’s worth a midpipe. I have the AA one on both my F80 M3 and F82 M4 GTS. Each car’s sound has been transformed.

I have catless DPs on my N3 with the MPE exhaust and love it!

The AA midpipes will transform the sound of your car with a lot of burbling ..You may feel little bit increasing in torque at midrange RPM.

Yes it does give hp and increased tq especially in the lower rpm range due to the pipe allowing quicker turbo spool.

Please see our in depth thread with dyno and videos explaining how it all works.

The OEM exhaust is very well designed, you will see little to no gains by swapping on a stock-turbo configuration. Merely changes the exhaust note, nothing else.

when installing the midpipe, you have to cut the oem section correct to fit the AA midpipe? basically rendering your stock section useless?

Cut pipes can always be welded back into place by a local muffler shop (or local independent) without issue.

Whoops looks like I misread the original post. I was referencing the downpipe if it wasn't obvious.

can anyone on the board, share their review on adding Mid pipes. Interested in before and after install, does it add power and in what range. thank you to both vendors at Active and EAS for replying but I'm still conflicted on this mod. Active has dyno sheet to show the power increase but Tom@EAS seems to state the opposite, as far as sound wise I know it makes a difference.

If you're looking for a different exhaust note, midpipes will indeed provide what you're looking for. Power, not so much.

Even a full Akrapovic EVO system barely made ~7whp on the dyno, the OEM system is very efficient without any choke points. BMW has done a very good job on this platform, there is not much you can do short of tuning, fueling or upgrading turbos in order to gain serious power.

Just bought the AA midpipe but purely for sound. Want to get rid of the rasp.

Congrats

Most of the full exhaust systems on the market are variants of the OEM design, perhaps with deleted secondary cats and a fancy muffler. Our system has a different design, and uses exhaust scavenging to provide an increase in torque and horsepower as proven on our dyno.

That is R&D for ya, would love to get the AA exhaust sytem but without valves it would be too loud for me if n noise control. Is it possible to add to the AA system or will you guys ever make a version with it? Thats the main reason I went for the mpe. Just wondering, thanks

Yes we have a new full exhaust system coming out soon! It will incorporate valves as well as single 3.5 inch piping from the downpipe back. Big gains and a deep exhaust note are the result.

Clip of it on my car for daily testing.

If you have any questions shoot me a PM.

Any incentives for owners who have the current aa exhaust system.

I can tell you the full AA setup is not very loud without downpipes. I have just the AA mid pipe and it's epic sounding if you install an exhaust flap controller. Power wise if you are complaining about the car running out of breath at the top end then that won't go away by making exhaust mods. The last 500 rpm on this car are not useful for going faster IMO.

+1

AA setup is not meant to be the most aggressive system out there, its the cleanest sounding one with no rasp.
If customer wants a more aggressive tone, adding downpipe should do it.
