I'm tired of the stock whisper quiet exhaust so I'm considering my options. I've read every post (yes, really) under a search of "dual exhaust" and I've spent a fair amount of time researching on the internet for various muffler brands. The most interesting muffler I've found is the "Aero-Turbine". I read all 24 pages of testimonials and although there isn't a testimonial from an Intrepid pilot, there is a very broad range of cars/trucks represented and several of the owners have provided compelling dyno numbers. Just wondering if anyone on this forum has installed the Aero Turbine.

Never heard of them. I'd stay with the proven, mainstream manufacturers...Magnaflow, Flowmaster, Borla, etc.... TRUBENDZ makes a pretty nice setup for our LH cars. I've heard some good things from the folks here who have installed their systems...

AeroTurbines are awesome. Many people with Dodge trucks love them and I personally like the sound (but not as much as I like DynoMax). I like them much better than flowcrapsters or magnacrap.

I like the Dynomax too, but from what I've read, they don't have a Camaro / Firebird type 1 in, 2 out, option like the 80 series does. (BTW, Re: "...flowcrapsters or magnacrap", I'm taking a wild guess here but I take it that there are a couple of muffler manufacturers out there that you don't like.)

I looked into the Aero muffler when I was researching my exhaust and seriously considered it. But in the end I opted for the 300M Special exhaust set-up instead. I think the Aero probably needs to be installed close to the engine to work right and my first muffler ended up farther back in the system so I didn't go for it. But I have no doubt that the 300M Special exhaust increases performance for a 3.5L HO - it actually changed the HP & torque curves ... :)

I've seen the pics of your setup, listened to your soundclips, and looked at your dyno numbers (BTW thanks for taking the time to post all that stuff). I like your setup for the efficiency and simplicity, plus it has a great tone. I'll probably go with the bling of faux dual exhaust. To correct what I posted earlier, there are at least three other choices for the 1 in 2 out system: Dynomax SuperTurbo, Dynomax UltraFlo SS, and MagnaFlow.

Making the last muffler a 3" IN/2x 2.25" OUT (or even 2x 2.5" OUT) won't change the performance of the system. It's the dual 2.25" tubing at the front followed by 3" mandrel bent tubing (ala 300M Special) that adds performance. Once you're to the back muffler you can pretty much do what you want as long as you have a total cross-sectional area of ~7 sq.in. (pi*9/4) ...

What do you mean by this? Do you mean closer than the OEM placement of the muffler? Why would you think that the Aero Turbine needs to be located close(r) to the engine in order to work? I'm not criticizing or anything, I'm just curious.

I looked at these a long time ago for my truck, but they were too expensive for my taste at the time and I more or less completely forgot about them until now. And as I read thru the testimonials on the site, I keep seeing some pretty remarkable and consistent comments on the increase in gas mileage. Since that's become an obsession for me, and with the price of gas being what it is, I'm really interested in pursuing this again for the Intrepid. But, if you think there is some reason why this won't work please let me know so I don't waste a lot of money for this.

In essence, the Aero tries to do for single exhaust what an "X" pipe does for duals - provide up-stream vacuum to enhance scavenging. The way I see it the Aero relies on exhaust gas speed to do this. The farther away from the engine you are the slower and denser the gases get. So it just seems logical to me that the closer it is to the engine the better the performance. If you want to try this I see no reason not to put a "Y" pipe and the Aero at the bottom of the engine down-pipes in place of the front resonator - it just seems like the logical location to me. But I'm not convinced it'll perform any better than my set-up. On the other hand I can't see where it'll restrict the exhaust either, so even if it doesn't help it shouldn't hurt.

Another option would be to take out the front resonator, put the Aero just in front of the first bend (in front of the gas tank) and run 2x 2.25" pipes back to it. The dual pipes won't cause much speed/heat loss in that short run ...

That makes sense to me, especially if you take their theory into account, it only seems logical to assume the closer you mounted this type of muffler to the engine then the better it'd work.

My first plan for a system was just about like the first one you described D76G12. I have a Flowmaster 2 into 1 "Y" pipe left over from another project, 2 - 2.5" pipes into one 3", and I also have one of their smooth transition cones left over from the same project, it goes from 3" down to 2.5". My plan was to mount the "Y" pipe where the front resonator attaches to the manifold downpipes. Then install the AT 3030, then add the transition cone directly onto that to bring it down to a 2.5" diameter system. From there, I was thinking it'd be nice to split off right behind the muffler to run dual pipes all the way back, but as an additional measure to get the right sound, incorporate either a set of Aero Turbine resonators to get that low throaty rumble that so many of us seem to want. Of course, if you like the higher pitched raspy sound, then you don't need to add the resonators.
