Fluid MotorUnion Product Release!

Fluid MotorUnion Product Release!


For the last five years, Fluid MotorUnion has made a business out of fabricating custom exhausts for a wide variety of vehicles. When we design such an exhaust, we’re doing so for one of three reasons:

1) The current market offerings cannot cope with the power we are looking to run on our projects.

2) We are looking for a particular sound attribute that we are attempting to amplify.

3) Current aftermarket offerings do not meet the needs of the customer.


Which brings us to our latest product release for the 04-13 Lamborghini Gallardo. While there are many aftermarket offerings on the market currently, we felt the need create something that could fill the void left by many other manufacturer’s products. Simply put, we wanted to make a system that provided a unique sound, increased horsepower, was made of high quality materials, looked beautiful, and showcased our craftsmanship. Only once these criteria were met did we then evaluate the price. Could we build something that could do all the aforementioned while being priced competitively? Could we offer more for less money? With all of these points as our foundation, we can proudly announce that our Lamborghini Gallardo Union V3 exhaust is available for preorder.



Why do we feel that our exhaust is the pinnacle of exhaust design for the Gallardo? We have been through a great deal of trial and error with various cars using our Dyno Dynamics dynamometer. Testing has shown us that power and sound go hand in hand. Every single thing we’ve learned along the way has been absorbed and utilized in the design of our exhaust systems. Regardless of what the aftermarket may want you to believe, it really isn’t that hard to understand what works and what doesn’t once the header ends and the exhaust begins:

-The easiest concept to understand is to only bend the pipes if you absolutely must. The straightest path between two points is the path of least resistance, and that lack of resistance translates directly to power output.

-In order to get a great looking weld, the pieces must be as close to each other with as little gap as possible. This is why we spend a large amount of time processing the raw pieces of pipe, so that they match up as perfectly as possible prior to the actual welding taking place. This is also great for exhaust flow, as there are no overlapping edges (and thus, no excess weld penetration) that can lead to turbulent exhaust flow, cutting down on power and altering the sound.

-We further minimize excess weld penetration slag by fully back-purging all of our welds with inert gasses. This prevents oxidization of the inside of the pipe. Oxidization creates a pile of slag that adds turbulence, cutting down on power and altering the sound. Back-purging also adds an extra bit of strength and rigidity to the weld and the system as a whole.

-We never use chambered mufflers. While it’s true that having the pressure drop from the chamber can add depth to low-end exhaust tone, that extra low-end depth typically comes at the price of top end sound cleanliness — often adding a hollow, whooshing noise. During our extensive work with custom exhaust setups, we’ve found that no matter what level of technology was used in the design of the muffler’s chamber, it never outperformed or sounded better than a high quality, straight-through resonated muffler design. That’s why we chose to use that straight-through design in our own handiwork.

-If a clean tone at high RPMs is the desired result, blending both cylinder banks together on a V-configuration motor is a must. Here at FMU, we hate exhaust rasp with a passion. To us, the high pitched, tingy, ripping noise is the sign of a design that is not optimal. That’s why we designed a smooth, high flowing X-pipe that allows the high-speed pressure wave from the exhaust pulse to be blended properly with the wave from the opposing bank. We never use balance tubes, H-pipes, or resonance chambers. During our years of fabricating, we have done a lot of exhaust testing on all manner of vehicles. We have seen countless exhaust designs, using all sorts of cited science and laboratory testing. There has never been an instance where we have seen a baffle, crossover pipe, or noise cancelling chamber that can best the performance and sound of a straight through, resonated stainless steel exhaust system. Our reasoning is thus — those three components we mentioned change the direction at or near 90-degree angles, which causes friction and turbulence, leading to power loss and sound degradation. We never use components in our exhaust that will drastically alter the laminar flow of a fluid, and exhaust gas acts as a fluid while in the exhaust system. Again, we are not saying there aren’t great kits out there that use these marketing bells and whistles mentioned, because there are, and plenty of them. If you are looking for the absolute best; however, we now sell a solution.


Simply put, there’s more to building a proper, powerful, and aesthetically pleasing exhaust system than just lining up pipes and welding them together. There’s a good deal of thought, precision, and effort that goes into every custom Fluid MotorUnion exhaust, and this product is no different. With all of the positives that we have promoted, you maybe wonder if there is a catch somewhere. Well as we always try to show transparency and honesty with our customers, I will tell you there is a catch. Being a small company, we have decided to make sure that production quality is held under our extreme scrutiny; therefore, we have decided not to have them produced by another company, but rather everything is done in house right in the U.S.A. This may mean long wait times as the systems are hand built. Please understand; however, that our reputation is everything, so getting a product to you that meets your time expectations is extremely important to us. Besides, were highly motivated, and the sooner we get the product to you the sooner you can be impressed by it.
