I will also order this midpipe with resonator and a 200 cell downpipe, we might end up with a group buy... ;-)

I didn’t ask for resonated with xpipe. Is there a reason to?

For me you made a big mistake not to go with the x-pipe.
Each pipe is going to sound like a "3 cylinder turbo", whether it's an x or y pipe you have to merge them to get a 6 cylinder sound.

Besides, it's completely useless to make 2 pipes the same length, as they won't even merge…
The EL only matters if you are merging flows from multiple inputs.

I got the midpipe in today. Everything was packaged well, welds were okay. I had to cut my axle back a bit more than what it was set to from my previous Milltek 4” single midpipe. This is paired to MaD resonated catless downpipes. There were no fitment issues and the polished finish looks great.

This setup sounds absolutely atrocious at anything other than full throttle. Crazy amount of rasp at partial throttle. Catted downpipes are going back on hopefully tomorrow.

Interesting, are you putting on stock dp's or 200cell ones? This is one reason i'm hesitant to change the stock downpipes.
How did it sound at full throttle with catless dp's?

I was going to put AA 400 cell DPs on. At WOT, it sounds decent, sort of like a VQ motor but not as trumpety. It’s interesting, at low RPMs, it’s very boomy and farty, mid rpms it gets quiet, and upper RPM it comes to life. I just spent an hour driving it home at different rev range and it reminds me a lot of the Active Autoworke EL. I didn’t get to take any more clips, but if anyone cares about low RPM tone, this is awful. It’s embarrassing with a resonated catless downpipe. This definitely does not sound like the X3M Active Autowerke Midpipe.

I’m debating taking the midpipe off. The single midpipe sounded way better down low, and was louder up top when I wanted it to be. The tone is a little more distorted than this EL, but overall the single and EL single (Valvetronic) wins in my book.

It seems catless + this midpipe is just not a good match, do you have stock dp's laying around?

I do but I would want a high flow cat to help with spool times. I’ve seen the logs from some of my customers with 200 cell catted DPs and the 400 cell GESI seem to perform a little better.

forcefed With your stock DP, any sort of unwanted noises at partial throttle like you going through a parking lot?

Is your axle back stock?

I was afraid that it would sound too raspy with any aftermarket downpipes, which is why I opted for the resonated version. If you have the AA downpipes, I would at least try it with that setup and see how it sounds before you ditch it.

Nope nothing
Here's a boring 12 min video of just driving around, at 2min mark i open the valves. Increase the volume, the gain was set low on the camera.

And some flybys

Am I seeing shit or does that bs brace have cuts on the spine of the first bend to make it bend easier? Is it back welded on that bend at all or anything.

Lol. Why is the little red car so scared of the other cars in the right hand lane when they go by that it scoots over? Does it have low self esteem? 😆

Damn this sounds good. I currently have Active Catted DP with their single mid. Wondering if I try this midpipe out with the Active Catted DP. My axleback is stock as I believe the OEM one is the best available option for reducing drone / no rasp.

No idea how it'll sound with a catted dp, maybe viciousmo will put one on and give some feedback. So far a stock dp sounds the best imo.

Yup, with no plans on changing them out.

[viciousmo]

400 cell catted DP on. It sounds nearly identical to forcefed G80. I didn’t have time to record just yet. So far, I am not hearing any rasp under various throttle inputs. Cold start still farts for several seconds, but I’m tuned so I can disable. Active Autowerke Midpipe also has this issue. This may be specific to a stock muffler setup.

Coming from 2 different single midpipe setups, dual bank midpipe are definitely quieter under WoT. I’m kind of up in the air whether I’m going to stick with this setup. I need more seat time with it. I’m making a smidge less boost in the mid range that I will need to get corrected with my tuner.

Good to hear, how much less boost is it running?
Don't know the inner workings of our ecus but the previous Bosch ecu in my car if I ran a bit less boost after a mod it would mean the efficiency of the engine went up so its running less boost to achieve the same power.
It's just like in colder weather, you'll need less boost to make the same power.
Any acceleration times differences?

About 1.2 less PSi in certain midrange spots. Peak boost is identical to my catless setup. WGDC will increase in those certain spots to hit the same targets as my previous catless setup. I haven’t Dragy’d it and likely won’t for a bit until I figure out what setup I want to stick with.

Which catted DP are you running and what previous single mids did you use?

I’m leaning towards the 4inch Milltek midpipe tbh over this to swap out my AA single mid and pair with my AA catted DP.

Active Autoworke GESI dp.

Valvetronic, Milltek 4'' single, and CSZ so far.

I gave it some thought and looked at AA's EL design for the X3M, which is the sound I was looking for. Although I know it won't be the exact same sound, I'm hoping I could get close to it as much as possible. They have an xpipe on their design so I've regretted my decision going without the xpipe. So I've asked Emily from CSZ if they could change my order to resonated xpipe with 3" diameter "equal length." She has confirmed that she could change my order since I ordered a custom midpipe from them. We'll see if the changes are made when it comes. I have good faith in them, as I've seen the x3m pages give high praises to their company through Alibaba.
