exhaust thoughts

[993RSClubsport]

Here is some more information for you to consider. Fabspeed Motorsports USA was the 1st company in the WORLD to design, dyno test, street and track test exhaust systems for all Twin Turbo Porsche cars. I was the 1st company to make systems for 993 Twin Turbo, 996 Twin Turbos, 997 Twin Turbos and Cayenne Twin Turbos. I made the worlds 1st modular system and was shameless copied by all the vendors mentioned from Italy to Germany and beyond. Fabspeed MAXFLO systems have been independently DYNO tested and proven to make more horsepower and torque than any brand from race only systems (no catalytic converters and muffler bypass pipes to 70mm 2.75" super high horsepower emissions legal systems that were co-developed by Evolution Motorsports and Fabspeed USA. From the Texas Mile, Las Vegas tuner shoot-outs to Tiptronic 996 Twin Turbo cabriolets we have you covered and with our modular systems you can go from mild sound to agressive sound in under 30 minutes. With a Fabspeed Motorsport Twin Turbo exhaust you can change the sound in ujder 30 minutes. All other manufacturers systems are 1 sound and not changeable. Everything we manufacture is T304 mirror polished stainless steel with HJS OBD2 European level 4 trimetal coating for no CEL lights. No mystery catalytic converters. Here are the Fabspeed Motorsports versions: VERSION 3-- same sound as Cargraphic Miltek. Gutsy European sound. Fabspeed has better internal exhaust gas flow for more power. Version 2-- Mild sound designed for Cabriolets and Tiptronic cars. No loss in power. Version 1-- Tubi sound with perforated core. Fabspeed designed this in 1999 and did NOT copy. Champion Porsche used to sell our systems for years. ------------------------------------- Louder versions: HJS catalytic converters with muffler bypass pipes-- popular "SLEEPER VERSION" you run the HJS catalytic converters and then 2 straight pipes connected by F1/Indy car V bands to the twin turbo tips. Car sounds like a 962 or 935 at Cold start idles and drivebys..........popular and not for the timid. Alex Ross Sharky had this on his car for years! Then Fabspeed Motorsports offers catalytic converter bypass pipes/ straight pipes to replace the Fabspeed HJS catalytic converters. You can easily unbolt the Fabspeed cats and RUN open. This would make any of the above systems a Fabspeed RACE SYSTEM. I was doing this back in 1999.........recently 9 years later TUBI and other companies have offered Race NON catalytic converter systems. This is old news. The bottom line is that you can get a quality system at a sound level that will appeal to any horsepower and Torque level with a sports car level that is suitable. Call or email Jeremy or Alex for more details and or stop by our shop.

I've got the Cargraphic. I suggest listening to some different exhausts at meets/shows and go from there. The difference in price overtime is small.

what exactly is version 1??

They only have 2 versions. V2(quiet) and V3(loud).

It is a great system and we are proud of it along with our other Agency Power exhausts for many other cars.

KA - you have the Fabspeed Version 1 which is their answer to those not wanting a louder exhaust. The Version 3 is the loudest. I would compare a Tubi or Cargraphic to the Version 3. The quieter an exhaust is, usually means the more restriction it has. I like the Fabspeed because they use HJS cats.

The other sponsors have good options too. Dont let price fool you though.

Betim at BBi Autosport makes the nicest exhaust I've seen. The sound and performance is amazing.

You get what you pay for. I think FVD is the way to go see: The search in finally over, exhaust & 997TT cab & .

(and I would try to avoid these fake tips, like Fabspeed or AWE tips. We don't drive fake sport cars, why should we have faked tips on them? The FVD is one of the few real 4 tips.)

Since this has been brought up a few times, I decided to look and see what this is all about. If I got the picture correctly, then it seems FVD is not any less "fake" than others on the market.

A true quad opening will have double outlet from the muffler. Here in this particular picture, the single opening makes that the point of restriction of flow, and the subsequent double opening makes FVD NOT any better than competitor, no?

No argument about sound or quality of FVD.

If you're going to be daily driving your Turbo, you definitely want to avoid drone.

The Milltek system is more aggressive than stock but not over-the-top. It also delivers ~25hp and ~25 lb-ft of torque over stock without a tune. It is made from 304 stainless steel, reuses your stock tips and features 200 cell cats.

In addition to all that, it's a VERY high quality system and easy to install.

Here's a clip of the system. We have one 200 cell exhaust in stock.

With that design they double the diameter, the others don't!

Double the diameter at that point does NOT make it a true quad. Why? The point of restriction is still a single pipe coming out of the muffler, the split that "doubles" the diameter towards the very end of the system is not any less fake than competitors.

A true quad would have four individual pipes coming out of 2, or better yet , 4 individual mufflers. In fact in the case of the Turbo, one could argue that a true quad doesn't exist, as there is only one exhaust/catalyst each per side.

I do agree though, that from customer reports the FVD seems to be an excellent system.

Below is a picture of a TRUE system, the GT2's, which has 2 openings, one from each side.




compared with the fake quad:

This is my EVERYDAY Driver "highway" most. I want to use my Cell Phone for my 2 hour drives. So I would like to find a nice quiet exhaust for the TIP that has 200 cell cats and good PERFORMANCE..


Thoughts?

In that case, I'd got with either the Tubi Street system, or a Cargraphic street system. Both will give you an awesome sound when you're on the throttle, but for everyday driving and cruising, you'll have no drone and cabin noise is minimal.

Thoughts?

Let me go through the bottom line first: You have to audition with your own ears as internet audio clips are unreliable. Pick reputable, established names and don't try to save money.

There are 3 separate issues:
1. Loudness
2. Character of sound
3. Performance

1. Strictly personal preference, and obviously a critical criteria. Most medium loud systems are not that loud at cruising so cell phone *should* be ok.
I should note that if you start out wanting quiet, there is a chance for regret as you end up wishing for louder (and vice versa of course, but I would speculate much less often than the other way around). So the advice is to go for the loudest system you think you would tolerate. The "right" loudness makes the car sound so good that you will be willing to sacrifice certain things. One example, I have the Cargraphic Loud, which despite of the name is IMO only medium loud system, which is not as friendly for mundane conversations, but in return it is pure ectasy when I slam on that throttle. So I readily and willingly take the exchange.

2. Again, obviously another critical criteria and again a matter of strict personal pref. One example of 2 very good and popular systems that people love: Tubi and Cargraphic. The Tubi (at least the first generation, there are now second gen Tubi's that I've not listened to) does not have as much low frequency rumbling as Cargraphic. Tubi is also more quiet. So if that low frequency rumbling and loudness are not important to your taste, then Tubi is the one.
Once again, if I have not said so , let me repeat: if possible, you must try to listen with your own ears if you are serious about this.

3. An after market exhaust is extremely beneficial for an ECU tune because it reduces back pressure, but by itself, don't expect much that you could "feel" as far as true power. All I felt after installing the Cargraphic is that the system seemingly pools up faster, but really there has been no official review/study that proves one way or another re. this faster spooling. There also have been anecdotal reports of some exhaust systems actually causing the car to feel weaker (less torque) in the low end, so I truly felt extremely lucky that my car felt the same, power wise, after the exhaust installation!

For Convertibles, 3 most oft mentioned systems are: Tubi, Milltek, and Cargraphic Quiet, mainly because they are more quiet than others and this might be desirable as convertibles don't have nearly as good sound proofing as coupes. That said, there are people who are happy with FVD and Cargraphic Loud in convertibles, again pointing the fact that this is strictly a matter of personal preference.

While we are on this topic, I should also point out that ECU mods *could* and do make any given exhaust system louder and shift it to a more stressful, higher frequency sound, and this varies from system to system. For a milder example of this, push the Sport button in your car and listen to what it does to the sound. An ECU tune will be similar in the change in character, except more so in intensity.
Also, if you are installing Cargraphic in anticipation of an ECU tune, I have been told by those who should know that the LOUD version allegedly/supposedly is the best because it is the most "free-flow" (least back pressure).


When you audition, keep in mind the car sounds totally different whether you're inside or out. While outside sound is nice for showing off LOL, inside sound is vastly more important for obvious reasons -- your hear this all the time. A good audition should involve riding in, or better yet, driving the car for as long as possible, on both streets and highways.

Click on the link in my signature to see my review of Cargraphic and detailed description of its "character" (basically, menacing, car shaking (I LOVE this!), low rumbling at low rpm, crunchy sound at mid rpm, and an absolute scream at high rpm). Surprisingly, I've become addicted to this sound and it's one of the highlights of my driving experience. I did not expect this addiction when I bought it.

[Tom@Rennsport-1]

^^ Great review and excellent points!

You're right about the Cargraphic loud being the "medium" loudness. They also have the "export loud" which is the loudest system they make.

[Casey@TPCRacing]

I would recommend Europipe... but it costs more than all of the others that have been listed. Makes 28hp though and sounds great.
