BMW M3/M4 AA Single VS. Equal Length Midpipe (Direct comparison) Which set-up is BEST for you (+M2C)

[@JordieMotive97]

The equal length absolutely sings like a beautiful inline 6

[@VinceFung]

It’s glorious especially up high in the rpm range

[@Neverworry21]

Causes too much back pressure and you can't hear the turbos

[@jvyyyy222]

Each has their own strongpoints; love the turbo spool of the single but loooove the tone and rasp delete of the equal. Definitely the best comparison video I've seen

[@VinceFung]

I 100% agree and you can’t go wrong with either, thanks so much for the feedback!

[@carsoncolemanbm4]

Omg that equal length really made it sound classic straight 6 w a hint of turbo spool! 🙌🏼🙏🏼 Sounds amazing! Both set ups actually sound really good but I'd I had to choose for personal preference I'd go w equal length! I'm all for raspy too so even to try the single would be an honor! Beautiful car can't wait to pick on up my self!

[@VinceFung]

I think you can’t go wrong with either. They both sound amazing in their own ways: the single midpipe has much more noticeable turbo spool, but with the equal length it just sings up top. Thanks for the kind words. Best of luck

[@carsoncolemanbm4]

@@VinceFung of course brother!! I love that white too. White is such a clean color. You can color match any wheels and there's a lot of room to work w for other coloring combos. I'm in a 2018 m550 right now and working on my n54 335 sedan and a 2014 m6 I'm in the process of rebuilding the motor and getting it track ready. They just don't hold the reliability that the M3 and m4 hold tho hence my reason for really wanting the M3 or m4. I feel like I'll get more beneficial track time w them and keep the other cars for show and just to drive! Can't wait to see more of ur build! God bless you brother!

[@VinceFung]

Awesome! It sounds amazing especially down low. Glad you enjoyed!

[@blendtecbrah5761]

1:24 ... we were all there at some point heh. I currently have mine set to 3200 RPM minimum and 0.6s duration, going to turn them down even more with my next setup. Even stock turbos howl like a banshee through the single midpipe! I'm about to swap mine out for a resonated EL... after the car makes a quick pit stop to have the factory cats reinstalled so it can pass emissions. After doing that dance it will be Eisenmann catless DPs > Active EL resonated mid > MPE. After living with catless/Active single mid/MPE for several years, IMO it's just too loud and flabby sounding. I leave the valves closed probably 95% of the time now. If it's not brought into check by swapping in the EL resonated midpipe, I'll probably bite the (big) bullet and throw some Active GESI catted downpipes on it. Going to rejigger the tune too so it's more "backfire" than burbles. Upping the minimum RPM to 5500 and setting duration to 0.2s. That way, it should give just one loud bang when you're really giving it the beans, and you can actually drive around with the valves open and not draw too much attention of the "unwanted" variety.

@@Ryco99-z2p I had the resonated EL mid installed this week and IMO it's a little bit quieter than the single mid, likely due to the resonator.

Great video Vince. Love the sound of your setup, doesn’t have the typical s55 rasp. Is there an issue with the main bearing on the s55? I’m considering getting an f90 m3, but not if there is a main bearing issue. I’m coming from Lexus, so you can maybe understand my hesitation 😅😅

[@TroungTran-g7v]

**f80

[@VinceFung]

Hey Truong, thanks so much! I really am glad I went with the EL set-up. There is no real concerning issue regarding the main bearings for the F8X chassis. Many have run and continue to run on stock bearings beyond 100k+ miles. I am also on the stock bearings and I purchased the vehicle with approximately 26k miles and now it has approximately 83k. Keep in mind however, these are all parts that are considered "wear and tear" and will eventually need to be replaced, just not as much as a priority. Needless to say I have very much enjoyed the car and still continue to do so lol!

[@TroungTran-g7v]

@@VinceFung well thanks a little more reassuring. I love these M cars, but in the past they typically have so many issues. Then I did hear about some f8x s55 having the main bearing issue, but doesn’t seem to be nearly as bad as the e9x s58. I will definitely keep it in consideration. These Lexus just don’t cut it when it comes to performance, everything else however, I love about them. Thanks bro 🫡

[@TheRyanEdits]

Great comparison! Do you find just the equal length midpipe loud enough? I’ve always done full exhaust with downpipe on my old subies so im wondering if id be satisfied with just the midpipe…

[@VinceFung]

I definitely find it loud enough! I’ve had just the midpipe for both set ups and find it to be the perfect volume. The only thing I would like is some spool but a catless downpipe makes these EL midpipes sound very farty down low. The best set up I’ve heard so far if you want more volume with the EL is the M performance rear muffler (v1/v2). Nothing beats that EJ257 though!!

[@Kxliderr]

Thank you! I choose to go with non resonated as I plan on keeping stock downpipes.

[@Ryco99-z2p]

@@VinceFungdo u think single or equal mp is louder when paired with catless dp?

[@VinceFung]

I would think the single would be louder with a catless DP due to the more direct flowing design vs. the equal length "zig zag". If you're going catless DP, I would definitely go with the single and avoid the EL as it tends to be really raspy below 2k rpms, with the DCT exaggerating tis even more. @@Ryco99-z2p

[@carsandcoldbrew6489]

@@VinceFung yup, the engine revs much better, or alteast sounds better with the equal length. Your set-up definetely matters as well bc being catless can make it sound awful without resonators. Catted (oem and high flow) sound the best without resonators.

[@VinceFung]

It definitely sounds mean! If I were to stick with single, I’d honestly probably go with ARM or something similar in that price range but I would definitely go catless downpipes with the single midpipe. As for the equal lengths midpipes, high flow catted downpipes are the way to go as it welcomes a putrid rasp on the low end.

[@Akac3sh]

[@VinceFung]

Agreed!!

[@philipsfilis3254]

Thanks a lot man, really helpful. I have an equal on my f80, but cant deal with the lack of body, etc, even with the swap of turbos, which improved the tone. Guess I’ll try the single with Dinan axle.. Does this intake sounds better then the Eventuri by any chance? Will be getting one soon.

[@VinceFung]

Not a problem at all, I’m glad you found it helpful 😃. I would say Eventuri sounds much better and louder, mainly because the AFE carbon intake I’m running has a heat box that may muffle the sound. However, I have not yet compared the Intake Air temperatures between the two intakes so I am not quite sure on which is superior. Eventuri looks a HELL of a lot nicer though as well lol! As for the exhaust, I have heard Dinan works well with the equal length. I have heard that catless downpipes will make it sound unpleasant, so I personally would stick with a high flow catted downpipe if you plan on doing downpipes. My current set up in this video is with the stock down pipes.

[@philipsfilis3254]

@@VinceFung Thanks man, guess Eventuri is the one. I had burger intake, but recently my F80 reached 620+ whp and the guy who did the job said burger is crap and the original intake of the car is actually the best, especially for better low rpm power, so i'm back with the original, but lacking the sound of the turbos. This mechanic did dozens, maybe more then 100 F80, and more importantly, he showed me in the dyno. He said that not even Eventuri is actually better then original, but as good, but if I want the sound so I should get it. And yeah, it looks really good.

with the el midpipe what dp should i use? also is there any way i could try and increase the turbo spool sound a bit? thanks

I would recommend a high flow cat downpipe with the EL. The best way to really hear the spool is to go with a catless downpipe, however with the EL I do not recommend it as there is a very buzzy rasp around 2500rpm’s, especially on DCT cars as it’ll hold around that rpm when driving casually. If you really want to maximize the spool sound without a lot of rasp, go with the single midpipe and catless downpipes. Just my two cents

I could not tell you to be honest as they both sound just as loud to me in the car. EL has just as much drone but it’s very minimal and at the lower RPM range (2k ish). But in a design aspect, it would make sense that the single would be louder but again I personally didn’t notice much of a difference. Maybe the ones you heard were resonated?
