Aero Turbine Exhausts
By Rick Reimundez
Generally, if you muffle the sound, you’re usually also stifling the exhaust flow – but Aero Exhausts uses a jet-engine-like turbine design that they claim improves air flow while keeping the noise police at bay. Not only do they claim performance gains over factory systems, but they also claim improved fuel mileage as well.
All of the Aero Exhaust mufflers and resonators are made completely of 304 stainless steel. There’s no baffles, or fiberfill in the mufflers – just the outside housing and the inside “turbine.” The manufacturer believes that the air flows more slowly around the outside of the turbine, then is recombined with the faster air flowing through the inside. The recombining of the air is what creates a vortex air flow within the muffler that helps to muffle the sound, but also helps to literally pull the exhaust gases through the muffler.
The Aero Turbines come with a lifetime warranty — against defects and to the original purchaser only. They compare the change in sound to the low muffling you get when you turbocharge a naturally aspirated motor.
They offer numerous universal applications for various exhaust pipe diameters so you can put together your own kits. I’d advise working with them to make sure that their exhausts and resonators will fit in your particular application, especially if it’s not listed in their application list explicitly. The mufflers and resonators range greatly in price from about $60 to just under $200.

Oh man, those are big fuel economy claims…

I’d be interested to see exactly how those mileage tests were conducted. They seem awfully far fetched for just an unrestricted exhaust.
The explanation that sticks out the most is this outer, slower-moving, cooler air that “literally pulls the exhaust gases”. Combining a slow gas with a fast gas doesn’t make the fast gas fastER in of itself. That doesn’t make sense.
What they probably mean is that the exhaust gas just inside the tip is faster than the gas inside the “turbine” which is true since you’re suddenly constricing the flow. However, the gases were decelerated at the inlet from the expansion in the first place. There’s no pulling, just pushing.
This is another example of overhyped marketing gibberish.
There seems to be quite a few positive testimonials on their website and this may very well provide all the claimed benefits of any other high flow exhaust systems but the lofty mileage claims and sketchy technical explanations leaves a bad taste.

I’m no physics expert but common sense tells me hotter gasses getting cooler slows down velocity and combining this cooler slower gas with even slower cooler gases forced through a restrictor plate = more turbulance and slower speeds.
According to their claims, if i put this on my intake is should create boost by their claims right?

The stock mileage seems more than a little bit low.

I have this exhaust on my volvo s40 and I have to say it is an awsome exhaust and the gas savings I recieve is about 8-10%…..

It’s an exhaust!!!!
