Exhaust Megaphone EXPOSED! FMUs OG viral fire shooting “F1” Lamborghini Gallardo system COMPARISON!

[@Lotarossa]

That’s my car I just picked it up today. They did a great job. It sounds smooth and the droning is now gone. The noise level is exactly where I want it.

[@Sun_Salt_and_Gasoline]

Sounds nice, but the OG exhaust X-pipe necks the whole system down to a single 2.5" pipe, while your old system kept the dual 2.25" pipes almost intact through the X-pipe. I think the OG loses a few HP when compared to the old system. OG cross section area is 4.90sq.in. through the X-pipe, old system is (let's say it lost 20% because of the cross-cut) 3.176sq.in. times two or 6.35sq.in. total.

[@FluidMotorUnion]

🤣 you think horsepower is made from diameter alone… none of the bends, length or scavenging play any factor in power huh? Number crunching 1 variable and discounting 15 years of experience from people who have a dyno and built 100s of systems is peak keyboard engineering…

[@ElMosqito]

I would like to hear two versions of your exhaust. With and without megaphones, and it should be the only difference. Only then we can judge the influence of said megaphones. As somebody stated already - your exhaust sounds best under load, and factory spec sounds best free revving

[@drewncars9505]

I think the stock exhaust in this particular example sounded the best free revving. The FMU exhaust sounded the best under load though!

[@rods715]

OG’s hair is legendary.

[@joeethereal2968]

[@Galli1084]

Just the hair!? Let's not overlook the Poisonous Ethiopian Caterpillar that's latched on to his lip.

[@Owlsrayne]

Excellent video, definitely noticed the difference in exhaust sound. Your FMU set up sounds so much better than stock. I learn more in each of your videos.

[@SpeedingTube]

The merge in the middle of the FMU X Pipe looks like it has the cross section area of just one pipe. It would be interesting if FMU took this further using an X-pipe with a 3.5” or 4” center and 2.5-3” entries to retain the x sectional area of both pipes. 2.5” exhaust area 19.6cm 3” exhaust area 28.2cm So 2.5” exhaust uses 3.5” x middle (38.5cm) And for a 3” setup, use an x pipe with a 4” middle (50.2cm) Just a thought 😎👍

[@JG-kv4oi]

The larger the merge in the middle (and to a greater extent the length or volume of the merge I'm the middle) the deeper or more resonate your tone will be. I have a merge approximately 4 feet long, cross section 2.5 x 4, makes great torque and quite resonate on a L98 Corvette. 😊

[@Thorfinn0607]

Man the first gen Gallardo 5.0 sounds amazing, it's so underrated, it existed way before LFA but a lot of people didn't care about it's sound back then and it got overshadowed by LFA, in my opinion better and it's cheaper, also more tuning potential, with twin turbos this car is a beast.

[@UKBUILT]

👍

[@ThePower1037]

Agreed, but it was a weaker engine because to get that 72º firing order, they split the crank journals 18ºs. The lfa made a race style 72º V block rather than the 5.0's 90º V. Making an even crank with an even firing order.

[@kasebuttram9542]

If Lexus would have made more LFA’s I think we would see much more custom ones. There was only 500 production models made (it’s been over a decade so probably a lot less from crashes now) so it’s a collectors item. Over 7,000 first generation Gallardo’s were made. They say 14,000 overall, but I think there was much more than that built tbh. But with that many built there’s more cars to market to for services

[@UKBUILT]

@@kasebuttram9542 yeah, I bet in the beginning of the lambo v10 tuning days there were alot of people blowing up engines. LFA is so rare you'd struggle to get another engine. The 5.0 lamborghini v10 sounds amazing, its the real screaming beauty. The reason we don't see to many tuned ones is the weak crankshaft. 5.2 lambo blocks had a stronger crankshaft design. I am building my dream V12 supercar with the OG zonda engine😎 Then maybe after I'd love to do a V10 build 😁 I have a 5.2L and 5L V10 engies ready for upcoming builds 💪

[@dinoferreira7950]

Absolutely love your content. I have an E92 M3 and I’ve been dying to find an exhaust that give it a high pitched v8 wail. The community has experimented with double x pipes, but I’d be very curious to see what you and your team could do 🤞🤞🤞

[@FluidMotorUnion]

Yea… don’t do double x-pipes. We did that in 09 on our E90 m3. X’s need to be front and center and need straight tubing to clean the sound back up. Closer to the rear the more “distorted” it will get and anything over 1 good X is overkill for any benefit to sound or scavenging. It’s a gimmick that will sound “different” than other systems but not the best the engine is capable.

[@michaelstables-ih1dv]

I have just recently stumbled upon this legend and his work. his content is next level. I came here to say that the S65 is arguably one of the nicest sounding V8s ever produced...like from the growl at idle combined with its distinctive mechanical noises that kinda sounds like stuff is loose and then the closer you get to redline which is ages away it just gets better and better:) I did bearings on a clients e92 M3 a while ago it had a pretty nice brand name system with no cats... it was beyond amazing the noise it made but it needed just that bit more and I reckon shopfront windows would of started exploding! if it was my car I wouldn't be chasing it and I would never get sick of it but I know the noise ur looking for. after watching this channel and I guess depending if you can package it correctly I'm sure this sound can be obtained. years ago I worked on a clients, clients E60 M5..that had the most ghetto straight pipe welded onto it they were terrible, it was obnoxiously loud but omg that thing sounded legit like a F1 car at full noise, but then at idle it was just a very loud noise and would probs never sound better than a v8 at idle.. again after seeing this guys content It makes me wonder what could be done with both these examples..I'm sure this bro and by the sounds of it, he has had played with these cars before, im gonna c what I can find about the M3 he had. if you live in the same country as him you need to plan a road trip with a bag of money and book ur M3 in for the 'experience' because this man's intelligence is somthing to be respected. and also my bro congrats to you for owning one of the last true M cars:)

[@DoAyBarrelRoll]

Have you tried this exhaust on a V10 Audi R8? I wonder if it will sound similar since the R8 Shares a similar 5.2L V10 as the LP Gallardo.

[@discipleoftheword1785]

Go bro!

[@KurumaDesigns]

Comparison videos like these are great, that gallardo sounds amazing with the fmu exhaust!

[@chrispompano]

In your Mercedes vid, you show a snapshot of the Paganni exhaust. It looks like it uses an equal length cone taper to the middle on both sides from inlet/outlet of the cone. Have you tried out a cone like that which is equally divided on both ends to the middle like the Paganni cones?

[@bogusphone8000]

Great work as always. What if you're looking for the opposite? Less high end and more baritone and bass. Think top fuel noise out of sports v8.

[@FluidMotorUnion]

So the inch per 100 rule, you’ll fall between it… more depth go bigger diameter available…. So a 515hp engine… instead of 2.5… you’d bump up to the next available diameter 2.75… 3… But understand you might lose a touch of torque on a NA car in doing so.

[@leveluplife8585]

Land Rover NV225 t case in the e53 x5 would be a mindful upgrade. The chain is half an inch wider and now you have a 2.69:1 low range. Dash, t case ecu, and low range switch is swappable if you make the crossmember brace custom.

[@ATStone]

Does the size of the X pipe need to follow the same size/horsepower rule? It looks like it goes down to the width of a single pipe there.

[@FluidMotorUnion]

intuitively it might seem like a restriction point but in practice you get x pipe placement and design right and it will keep exhaust velocity high via the timing of the pulses. This creates a venturi effect, pulling exhaust gasses out of the cylinder head. I assume most have figured this out like we have as this design remains fairly constant in the aftermarket gallardo exhaust designs. If you look up the dyno results for the spit true dual systems, not only do they NOT make the best power, they also sound atrocious, with the only seemingly redeemable quality being a low price... So to answer your question directly, it can- if you don't place it right, but if you do, the rapid restriction to expansion and resulting pressure change next to a venturi suction can aid in total flow.

[@ATStone]

@@FluidMotorUnion Awesome, thanks for the detailed response!

Some of it is undoubtedly camera microphone and online sound processing that falls short of what your naked ear hears at FMU. I guess this is why audio engineers are expensive in the business of sound.

So I have a question… Is a muffler mid pipe a disruptive flow inhibitor? So, is replacing the X pipe configuration with your muffler slowing down velocity? Small hole to big hole degases suggests an absolute yes. But!Depending on where it’s situated will the exhaust gas velocity slow down far enough away create negative affect upstream?

[@FluidMotorUnion]

Depends on the style of muffler and heat the system is carrying… but don’t use chambered mufflers and it’s not something that you’ll have to worry about.
