What Is The Best Midpipe Sound & Performance

[MYBOYBLU3]

I currently have Eisenmann catless DP's and thinking of the AA single mid pipe…have 0 clue how it will sound.

I haven't been on the forums in so long and thought the equal length was the way to go going by what Youtube says. Now reading here it seems like it can go both ways, and now Im so confused

both work, it's just a completely different sound.

Some customers want a cleaner rasp free turbo sound, that's your single

others want a deeper mid-tone, almost non-turbo like, that's your equal length

Respectably, this platform sounds embarrassing with anything other than an EL exhaust or a Single Turbo conversion. I'm not even being hyperbolic, I would have not bought this car if the EL offerings were not on the market, they really change the car for the better. I don't even like to cheer for a company or corporation, but Active Autowerke really has a golden product for the F8x platform IMO with the EL midpipe.

Just my 2 Cents.

Really? So it doesn't "lose" power at all? I don't expect gains— i'm chasing sound/no power loss.

It didn't feel any different to me.

i switched from single to non-res equal length to res-equal length.

did not feel any power loss either

You're talking about going from OEM to single mid, right?

I went from stock to single, don't remember feeling much difference.
Then went from single to equal length. Dont remember feeling any difference there either.

This. Love my EL.

The extra bit of drone is noticeable in the first 2 - 3 min of driving, after that it quiets down. If you are tuned via BM3 or similar you can bypass the cold start I think. It didn’t bother me enough to do that.

The EL sounds the best!!

Great. Just saw your Black Friday sale and will head over to check it out.

Gonna likely go for the single midpipe then. Looks like I still have the factory setup on my new to me '16 M4 coupe...Sounds like best of both worlds and less risk of drone.

Is the start up drone and general drone reduced with the resonated set-up? I'm drone allergic and have a stock zcp and want to go resonated AA EL

it does

so drone is reduced with the resonated yeah?

resonated will reduce the sound exhaust, this includes the good sound and if any drone is present

I'm sure it would be, but I didn't have the non-res pipes on my EL until after I had deleted cold start with bootmod3.
Deleting cold start killed the drone completely. The only time I have ever heard it drone since then is when my exhaust flaps were temporarily unplugged. The flaps are opening and closing all the time to prevent resonance (drone), so if you crack them wide open all the time it will drone with just about any exhaust, IMO.

If you delete cold start, and you're planning on keeping the stock muffler and downpipes, I recommend the non-resonated version. Much more/better sound.

You won't get great sound with a mid-pipe alone. The muffler plays a large role in sound. One option is Fabspeed mid and MPE muffler. This combo is one of the best sounding but be prepared to wait an eternity for the delivery of the mid-pipe if you plan to order a new one.

The non-res equal length mid is a great start, though, if you're keeping everything else stock for the time being.
I just sold my Dinan muffler and ordered something else, and I am not miserable with the stock muffler while I wait. It is 5,000,000,000 times better than the stock midpipe sound.

It's personal preference, really. But my experience has been the following:

single midpipe: no rasp, no drone, car still sounds like a fart.

equal-length midpipe: no rasp, some drone when the pipe is cold until I deleted cold-start, sounds MUCH better than stock or single.


EDIT: The equal-length did NOT sound good on my car with high-flow catted downpipes. I put the stock downpipes back on for that reason.

You need resonators to make it sound good with high flow cats.

Did that. Didn't like it. Car sounded like a Honda.

In fact, at one point a late model Civic Si came through an intersection just before I pulled away from the traffic light, and the two cars sounded almost identical. I took the downpipes off a week later.
