I have about 6,000 miles of experience with the speedART Export system. That's the more aggressive choice. It can get loud under certain conditions, but when cruising it sound nearly stock. Stick your foot in it, and WOW....!

Yes, these systems are pretty much the same, as stated by 06cs. The system is really made by M&M Power of Germany. SpeedART actually helped design it. In fact, speedART handed over their Cayman S as a development car, one of the first on the streets back in 2005. They now make this system for a number of companies including speedART, FVD, Farnbacher Loles, Gemballa, and some others.

I don't suspect you'll find any significant differences between the different brands. So the choice basically comes down to company integrity, reputation and service. I chose speedART because of their long standing support of our club, and because they and GMP Performance (the U.S. importers) are real stand up folks. I wish I could say the same for all the companies that sell this system, but I've seen some really dirty behind the scene politics that really concerns me. I suppose that's another story.

PM me if you have any questions.

Have you ever measured Decibel sound levels? What about analysis of frequency composition of sound at different rpm and load levels? In other words what is the scientific essence that makes one exhaust more appealing than others? Gator,with your knowledge of audio and exhaust you might be the one who can answer this, or perhaps it's just a stupid question??:cheers:

Not a stupid question at all.

At the risk of sounding glib (no jumping on the couch!), I think the best answer to this is, what makes the hair on your neck stand up when hearing the exhaust?

The answer to this will be different for everyone. The other important thing to consider is how an exhaust will sound inside the car since you'll be the person living with it.

Search for our CroctoberFest 2008 Exhaust shootout video on the site. A lot of good information on there with measurements, etc.

I realize it's all pretty subjective when a final choice is made. Not being an Engineer I just wondered what "scientific approach" one might take in designing the tonal qualities of a particular exhaust system. I want power when I feel like it,raucous noise when I open it up ,and relative quiet the rest of the time. Imagine all this and I don't even have the car yet.:crazy:

Where did you get this information?

We did measure decibel levels at Croctoberfest 2008. The speedART came in a little lower than the others, which is consistent with the fact that it's a little quieter. But it's the tonal difference that makes it so different, and as you've pointed out, it would be hard to measure/articulate/visually demonstrate that. I suppose a spectrum analyzer graph could help you see the difference, but it's not that easy to show you what something sounds like.

You can get spectrum analyzer iPhone app for peanuts. But I have yet to validate how accurate it is...

Update:

Just got back from a drive down to seattle (4 hrs round trip) The ride was very comfortable without any overpowering drone at cruising speed. I was fairly light footed and averaged about 70mph straight highway. I managed to get 26.8mpg for the trip! Thay may be equal or better than stock if i remember correctly. I think i managed about 24mpg with no mods. the SRP improves mpg while the exhaust worsens. I think this exhaust definately has a mpg improvement over my AWE as i was never able to get such mileage with the latter.

man i love my car....

Does anyone out there have this FVD/M&M exhaust (Export/Loud version) on a new 2009 Boxster S with the 3.4L DFI engine? If so, what are your impressions?

 

[force4rmr]

I"ve have this FVD exhaust as well on my 07 CS for about a month now and LOVE IT! A sudden change of plans however has me moving on to another car and I'm selling my CS. So the mods are coming off and this exhaust has to go. It's in the classifeds at a very reasnoable price if anyone is interested.

 

[sixisenuff]

it's hard to explain depending on your definition. which exhaust are you comparing to? under part (up to maybe 50%) throttle, there is no drone. if you floor it in that zone, you will hear some noise, but it is not distracting or loud like the other systems. whether or not i classify it as drone or not is hard to say.

since my version was the louder sport version, they also have a TUV version that should be on teh quieter side if that's what you are looking for.

I have the TUV and it's much the same. You can make the exhaust make more more noise than stock in the car but it's ridiculously easy to drive around. You have to give it quite a bit of gas at lower RPMs. Not a cruising issue. I'm really not flipping crazy about a lot of noise in my car and and I think the export version would have been fine for me. The TUV may be a little too tame, even for me. Still better to have it like this as most of these systems gradually get a bit louder with more miles.

Driving around with wifey in the car is no problem with this exhaust.
