Aero Turbine Mufflers? Maybe.. Maybe not...
 

I tried using the search feature and google'd this forever. But I just cant seem to find anyone ever using a Aero Turbine mufflers on the rx8 before. I have a aero turbine 3030 on my v8 dakota and a 2540i on my 3g eclipse gt. Both have changed the sound amazingly on both vehicles and as cliche this may sound my mpg has actually went up 2-3 mpg on both vehicles. I want to be daring and attempt to install 2 aero 2525 mufflers. You can check it out here.

But I'm not really sure if its a good idea or not. Or should I just go with a complete custom cat-back exhaust from either Mazdaspeed or Racing Beat. The main thing I really like about these Aero Turbine's is the unique sound they give off and the deep mellow tone. Anyway let me know what you guys think about this idea. I really appreciate it.


Thanks

The shape reminds me of the Corksport catback mufflers.

I have also used Aero mufflers on alot of my cars. Honestly, they sound AMAZING. My plans were to replace my mufflers on my AP exhaust at one point with these and try it out. Its probably going to be awhile before I do it though. Here are the aero mufflers on my Z.

camthman that sounds amazing on your Z what setup do you have? I sure do love the sound of Aero mufflers. I may do two 2525 mufflers and aero tips for my 8. I'm sure i'll love it. But hell if I dont I can always go with mazdaspeed cat back at a later date.

Based on how that 350 sounds you should do this and get back to us :)

I have a 4" one installed(the one with the silenser part) in my middle pipe before it splits into two 4" round mufflers at the rear. It took all the "fart can" sound out of it and it sounds great.

Don't know about 3" but I assume its got to be even better.

Best regards,

Chris

Yea I think I'm gonna give these aero's a shot on the 8. Chris the 4" one your talking about is that the muffler with tip correct? If so I have the same one on my eclipse sounds great. I just have a few questions for you. Does the muffler with the 4" fit between the plastic wholes we have on the back of the 8 or did you have to customize it to fit? If it does fit without customizing does it melt the plastic at all? If fits and does not melt the plastic I may just go that route and pop those two on the back. Originally I was thinking of just replacing the two oem mufflers with the aero 2525 or 3030 and adding the aero tips at the back. Also you added in the aero resonator, with the mufflers alone does it make the 8 sound extremely loud? Did the resonator actually tone it down a bit so its not so honda civic "fart can" sounding?

Any sound clips?

My question is how loud are they? Tone and muffling ability are 2 totally different things. What muffles a piston engine well doesn't always do much on a rotary.

Yea my same exact thought. Hence why I cant find anyone that has an Aero on a rx8. Chris you need to find a way to get a sound clip of your 8 pronto! haha :naughty:

Ya know, whenever someone tries to "sell" something, and then tells me it increases mpg, I automatically become very skeptical of the product itself.

This sounds like it's on the pantheon of electric turbine kits.

When I got the aero turbine mufflers for my other cars I never really cared for the statement that it increase mpg, mostly bought it for the sound it gives off. Since I have a 90 mile commute during the week I noticed that I dont need to fill up every 4 days now its about every 5 for my eclipse. So I can now last mon-fri on the same tank of gas. Before the aero muffler and k&n filter my tank lasted about 400 miles per tank now its about 450. I doubt it will make any affect on the 8 but it might say give an extra 1 mpg or so. I just really want to hear what these mufflers sound like on a rotary as I've only herd them on piston engines.

So, it's the one with the resonator they say to use on the RX8. 2525XL

I was thinking more about this. 304 Stainless melts at around 2650 degree F. I your were to build a custom midpipe, and place a 2525 up front where the cat normally resides, it should see temps below the melting point. With no packing to melt away on the inside, this might quiet the entire exhaust system from the manifold back. I was logging cat temp's around 1800 degree F, so it should hold up.

Tell, you what. I have an old RP supercat pipe I have hacked up , but never finished building my custom midpipe. I will guinea pig this and build a one off.

:Eyecrazy:

Awesome! So your gonna go ahead and give the Aeros a try also? I think I'm going to do two 2525xl's on the 8. I talked to ChrisRX8PR and he has 3 4040xl's at 4" in the Esmeril Racing turbo'd black 8. Hes got a clip on streetfire.com of the 8 driving around but not really an exhaust clip, but you can def tell its there. Sounds great, but I think the 2.5" or 3" will sound better for a N/A 8.

Im glad you guys liked them on my Z. FWIW, the quality is amazing on them, and everything I have thrown them on has sounded GREAT. I also have them on my SVT contour.

Aero mufflers on the svt contour.

Yeah they sound great on a Z yours specifically, I think better than Nismo personally. I just got my 8 back from the shop and I cant wait untill this weekend. I'm going to put on the aeros and see how this baby sounds and feels. I will def post up a video!

In looking at the length of the 3030, it says 20" and that might be tight where I want to place it - up front where the cat resided. I think the 20" is including the end pipes. Wonder what the actual 6" muffler length is...

Any pics you want to share??

I had to search for this, but here is the video of ChrisRX8PR Black 8 on street fire.

I have a used aero 2525.
i'll sell it for 75 shipped.
pm me if interested.

Done! I went ahead and did a Single sided cat back with an Aero 2525 on my 8 and a 3" tip. The sound is great... has a very low rumble and very minimal rasp. But in high rpms my god is thing loud haha. I made a couple people jump out of surprise during 1st gear at 8k rpm coming from a stoplight, even made a lady drop her cell phone. I felt bad but she shouldnt be on the phone while driving anyway.

But all in all I like the setup. Only cost me 250 to get done. And I'm pretty happy with it. Do to it being single sided I probably got +1 hp in performance wise... Woohoo!


Pictures and video coming soon!

Stay tuned!

Cant wait for those photos.

How does this muffler look inside?

adamwzl;
do u still have the stock cat or you have a midpipe/high flow cat?

Yea I still have the stock cat on and the muffler is a straight through design. Tomorrow I'm going to get a video clip and pictures taking after work.

Whats the difference in design compared to a resonator (I thinking of internal design)?

Check out this video here its a short clip explaining how the aero mufflers work.

Ok now im getting really interested in this.

I want Pics and Videos with that on a rx-8 now! =)

haha working on it as we speak :)

Ok everyone here is what you all have been waiting for PICTURES!!! and VIDEO!!!...
This is a aero 2525 Muffler with a 3" tip single sided.

man, it looks and sounds great, but i personally can't stand doing a single exhaust setup...

^ it doesn't bother me a whole lot. I really wanted to try one of these mufflers on the rx8 its pretty nice I like it. But I'm going to get a RB cat back over the winter though. I do love the dual..

It sounded just like mine but mine was with 2x 3030 dual setup. It was loud as hell even with a turbo + high flow cat + magnaflow 4" muffler, so i took these off and installed a burns stainless muffler and 2 borla xr1. It's so much livable now.

Hmm.. sounds interesting. Did you just get tierd of the aero sound?

That's my biggest concern over this system. I just don't see how it could muffle all that well. I can see how it would do a little though. I know they claim that jet engines use this type of technology to help quiet them but that's a little bit deceiving. A jet engine, specifically an airliner jet engine, is a high bypass design. This means that much of the thrust (up to 80%) can come from the compressor stage of the engine itself as it bypasses the combustion chamber. Only a small amount of the air that gets compressed actually continues on through the engine to the burner cans (combustion chambers) and then out through the turbine wheels. Much of the thrust is really nothing more than a series of fan blades directly acting on the air.

This cooler, noncombusted air that travels around the outside of the engine completely engulfs the hot air at the rear of the engine. It completely surrounds and mixes with the higher energy air which helps to muffle it as well as cool it down. This is what the aero turbine muffler claims to do. It splits of the air and causes a temperature differential where the cooler air travels around the outside of the inner hotter gasses to combine at the tailpipe, supposedly having the same effect as that in a jet engine. It sounds good on paper. However the temperature differential isn't all that large comparatively and the amount of energy between then is roughly the same rather than the a high bypass having far more cooling airflow present.

I see this technology working in a small way but if it truly did anything useful to muffling, they wouldn't recommend a system that had a conventional muffler as a presilencer. I'm sure it does affect exhaust tone though which is what I suspect they are really hoping sells these. I jsut don't see them working too great as a dedicated muffling device. The real test would be to put one on an n/a 13B which has a far harsher exhaust note than a Renesis.

Yeah they dont work too great as a dedicated muffling device. If you want queit they have the XL versions which include a resonator inside of the muffler which brings the tone down a bit compared to the one I purchased. The sound is loud to me at high rpms and it gives it a deep rumble when idle, I purchased this exhaust system for sound alone if the other information mentioned was true thats just an extra bonus for me.

Really nice, I would like some incar and pass by videos as well.

Does it sound too mutch incar?

It seems to be enough space to fitt these mufflers also?

Alot of questions but im thinking of making a catback with these as a winter project just for fun. Would be cool to have on these free noise level trackdays. =)

I can work on a in car and pass by video once I get someone to record for me haha. Under load it real does scream..


While driving the only time it really gets to loud for me is when im WOT. But other than that its pretty much a low rumble.

Selling this Single Sided catback.
