20 Dec Best Sounding Audi R8 Exhaust System Without Any Drone?!
Looking for the best sounding Audi R8 exhaust system? Fluid MotorUnion in Naperville IL can help you out! Our system is fabricated using quality 2.5” diameter 304 stainless steel along with our optional “straight-through” resonators, our Audi R8 smooth-merge exhaust system is sure to make you smile while not aggravating your neighbors (or wife). Our system is designed to make your R8 sound how it should have been delivered from the factory; won’t drive you or the cops crazy while running around town or cruising down the highway, but downright exotic when you decide to step on the gas and have fun.
Fluid MotorUnion is also equipped to take care of all of your exotic repair needs. Recently we helped a customer who was in need of a replacement clutch in his R8. Check it out here
How did we build the best sounding Audi R8 exhaust that our customers rave about? Here are the fundamentals:
-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 strong and 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.
-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, tinny, 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 a variety of different 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-canceling 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. However, if you are looking for the absolute best, we can build it for you.
Enjoy the noise!
