they do have a variety of different tips, btw i looked at AWE's website,

i guess that the muffler design is similar - of course without the valving for the sound control function. The 9ff steel looks thicker is this possibile? or is all this stuff made of the same stuff?

ps I agree that the website is kinda eh..."euro", but whats up with all the "i dont like 9ff as a company?" whats going on here? i did hear about some issue where supposedly someone got ripped off by the usa dealer. Apparently 9ff corporate stepped up and took care of it. Amazing how bad info travels faster than the truth on the 'net.

Holy Crap Batman, glad I have a mute button

I just wrote an e-mail to 9ff with a bunch of questions........

Hello,
Myself and several other Porsche 996 Turbo owners at Rennlist.com are in the process of selecting an aftermarket exhaust. Your company name came up as an alternative to Fabspeed, Europipe, Cargrahic, AWE, etc. and we like the fact that your product has a bypass feature like the Porsche Sports Exhaust.

Unfortunately, none of us are familiar with your products and the website wasn't much help, so I have a few questions:

1. Price of the 996 Turbo Sports Exhaust?
2. Is Eurocar Boutique the best place to order from in the US?
3. What are the materials of construction (assume it is a stainless steel alloy)?
4. What is the tube size (pipe ID)?
5. What are the HP/torque gains, and do you have dyno tests where only the exhaust was added from stock?
6. Do you have any video or sound clips with the exhaust bypass open and closed under a variety of conditions (idle, hard acceleration, etc.)
7. Does the exhaust have resonance (drone that cause a headache (ie Fabspeed) in the 2000-3000 rpm (cruising) range?
8. What density cats does the exhaust use (ex. 100 cel, 300 cell (stock))

I'll post the answers

qirex, it has nothing to do with the us-dealer. it is more the non profesional trial and error attempt to get a V-Max record at the Nardo track. There have been at least 2 reports on german TV and in our biggest sports car mag. At every attempt there were at least some stupid problems like a bad suspension, a drilled water tank, a wing that did not function and so on. The record they did was with the mirrors and the wiper removed.

It always seems that the ex-ruf tech thought "what mr.ruf does seems easy, so why not earn the money and the fame myself?..."

They sell their "record" cars for 100K - 350K Euros on www.mobile.de

Whatever, I also don't like the approach building cars with very big turbo and enormous lag only to provide some top speed. Those cars are sure as heck miles away from the ruf standards.

What looks nice is that they add water injection to cool the intercooler and so on.

You asked about a muffler and I tried to answer you. Whether I like or not 9FF is irrelevant, I have just answered your question about the exhaust.

Truth?
There is a friend's 9FF car(800hp engine, 100k Euros "invested" in it) here that has been sitting in the workshop for 7 months after having run for about 5 days. 9FF did nothing to send someone to fix it yet (until 2 weeks ago, haven't checked since).
That does not mean that I do not like their exhausts, if it is sound and build quality you are after, but I know why I say that I don't like them.
I also have not seen their cars going beyond 50k miles yet without issues.

I spoke to the Todd Yasuda of 3T & Associates at the German Autofest today. I looked at the eff exhaust and got the following information from him.
The exhaust is $6500.
It is made of stainless steel alloy.
It makes 31 hp at thw wheels in the byass mode.
It makes 12 hp in the muffler mode.
It uses the stock cats to attach to.

I spoke to Todd Yasuda, vice president of 3T & Associates (the US distributor of Sportec and eff products) at the German Autofest today in Ventura California. They were exhibiting there and are located in the City of Industry which is about 45 miles south of Ventura. I looked at a the eff exhaust and got the following information from him and offer these observations:

The exhaust cost is $6500.
It is made of stainless steel alloy.
It makes 31 hp at the wheels in the by-pass mode.
It makes 12 hp in the muffler mode.
It uses the stock external cats to attach to.
It appears to be built very well (almost overengineered).
Without the cats it feels very heavy (I would estimate 35 - 40 lbs.)

If it works well it could be a very attrractive alternative for those of us who want to "have our cake and eat it too."

Terry Ball @ 3T Associates says they have (1) unit in stock (9ff) with adj sound control.
$8015, which is a little rich for my blood but certainly looks like an incredible exhaust
"system". I have no affiliation to them whatsoever. (626)-369-2222

$8000 for some bent tubing? And I thought $5k for a Europipe was bad.

Honestly, I would pay $3k for a decently constructed exhaust without resonance with reasonable HP gains, and maybe another $1k for an adjustable system.

I can't help thinking some enterprising welder who knows something about cars couldn't meet this.

Woodster

the best systems appear to be around $5000 and up...
Euorpipe == $ 4945
PSI == $ 5000-5300 (both listed are made in Belgium)
9ff == $ 8000
Kreis-sieg == $ 8889 (stainless)
== $ 15, 989 (titanium)

maybe PSI and Europipe are worth it???
mk (Have PSI quiet on order)

Hi Woodster,

The Europipe Stage II Quiet is probably the most frequently installed one here. Nobody ever comes back complaining of resonance or drone on that one. The Kreis Sieg is one I would stay away from. A customer of ours had one and due to the design it cracked. I don't feel having a single canister without any flex that's bolted to the motor which does flex is a good thing. Especially with the heat, it's only a matter of time before it cracks etc....

We also began installing the new Quiet Sport Exhaust from EVO (made by MillTek):
http://www.sharkwerks.com/products.php?pid=43

It also doesn't have resonance but it is a bit cheaper....

Shark

Any dynos or video clips on this new EVO exhaust Alex?

Are they planning on making a louder version (also without resonance)?

How about a bypass adjustable system, wide open.....who cares about resonance, muffled......a quiet cruise to work at 6:00 in the morning

sharkster

Hi Shark,

Sadly what dynos I do have thus far probably aren't the most useful. I have dynos of the exhaust on already modified cars. Basically cars that already make power from a chip, turbos or something else... It's so hard to find a stock 996TT these days I can post the dynos of the results like other guys do but just make note that the cars are NOT stock to begin with Just want to make sure you guys know that...

Todd uses it on his 950HP TT as an FYI. Also, MillTek is a great outfit for Audi Exhuasts so they know their stuff

FVD Export:
w/100 Cell Cats$4295

All under 5K, provide good power and NO resonence!

I forgot FVD (and Cargraghic),
FVD has very good products!!!

Interesting that Terry Ball quoted a price over $8,000. Naoki Yoshizawa @ 3T & Associates quoted me a price of $6,500 for the adjustable unit. I'll call them tomorrow to get an explaination on the price differences.
