997 GT3 RS exhaust options
Subscribe
I a have been away for some time and I want to know the GT3 gurus what is the best exhaust option now.
I have friends with Sharkwerks by pass and AWE GT3 system.
Are still popular options or any new option?

Sharkwerks just released a track exhaust. Here is a nice video clip of it.

You cannot go wrong with the bypass pipe but if you need it a bit louder
, the track exhaust might be right for you.
Plus, Alex and Sharkwerks has the best customer service.

There are a few choices out there and there's room for discussion.
Here's what I went with for my GT3RS. It saves 51.8 lbs
Here's a little video
http://www.youtube.com/watch?v=ZDMLssANQAo
I haven't had the time to put all the info, stats and results of the development of the system w/ FVD and M&M.
It makes power and is loud. The revs are crisp sharp barks without any rumbling or gurgling.
Anyway just a thought to think about. I LOVE IT. Right now there are only two systems in the US (both in So. Florida).
Best of luck with your decision.

Love those RSR style tips Ranger! Did you ever end up ceramic coating it?
To OP, there are so many options out there that I can think of off the top of my head, but it seems like the majority go with Sharkey's bypass pipes. One of the best systems I've ever heard was on another users named mdskipper11. He has a full titanium akropovic system and I believe it's the only one in the country, but it is VERY expensive.

It is by no means cheap, but I don't think you will find a system with as much R&D in it then our A.W.E. Tuning complete exhaust.
Early testing found that while just removing the rear section may sound nice, it did nothing for power.
So we studied the Cup and Cup RSR systems and formulated a design that will not only add much needed volume and tone, but will not lose any power across the rev range which is common on exhausts for normally aspirated cars. If you notice our dyno sheets there was no dip below the baseline run!
IIRC, we have over 150 dyno runs between two different test cars.

- 200 cell German HJS catalytic converters
- Thick 14 and 16 gauge 304 Stainless Steel mufflers and tubing
- 16 lbs weight savings over stock
- TIG Purge Welded for highest weld strength
- No loss of ground clearance
- Optional Diamond Black tips
- Optional tailpipe turndowns for track noise limits

Some advice from someone who is not trying to sell you an exhaust:
Full exhaust systems are a big waste of money. everyone knows porsche didnt leave much of anything on the table with the exhaust.
the stock header is about as good as it gets. its used on the cup cars and is well designed. stock cats flow very well and 200 cell cats dont have anything on them.
whatever you choose, just get a cat-back with either a by-pass type system or a complete muffler delete system like the sharkwerks race exhaust.
race system saves about 50 pounds and bypass saves about 15.

It is by no means cheap,
After all the research I did on a full GT3 exhaust...it is a small fortune one will have to spend to get one of these, then you add Ti into the equation then it is a medium fortune. I assume most of the cost is in the R&D for each company I looked at. price range I found 10k -20k
so for me it comes down to sound vs sound and performance....and of course weight savings.
SharkWerks or RSS will give you a finely tuned sound, with VERY well made pieces, and some good weigh loss, all at a reasonable price.
Spending over $6,000.00 for less than 10hp seems like a lousy ROI, but it's all subjective at that point.... Hell, some folks spend over $5k to bubble wrap their car.....

We chose the Sharkwerks Track Exhaust for our Car.. I am 100% satisfied with it after over a month of Daily Driving the car.. Below are some details Quoted from Alex @ Sharkwerks.. Any questions feel free to Pm me.. Thanks!!
Mike
The SharkWerks GT3 Track Exhaust system, which has been designed, developed and tested on our 2007 997 GT3RS (ZKERMIT) and 2010 997 GT3 shop cars, dramatically reduces the weight in the rear by 57 pounds. Utilizing two lightweight stainless steel race mufflers (each weighing two pounds) and three inch stainless steel piping, the entire system weighs eleven pounds and looks much akin to a Cup car set up. Installation is made easy via the use of stainless steel CNC'd flanges. Factory clamps and ceramic seals are retained for an OEM seal at the header/catalyst junction.
Here's a video we put together showing the product, installation and dyno tuning:
http://www.youtube.com/watch?v=15SD8XYFX2Q
Features
- Cup car derived, VERY aggressive sporty sound (see videos)
- Real 57 pound weight savings from the rear of the car
- Aggressive slash-cut 3" tips
- 18 gauge T304 tungsten inert gas welded stainless steel
- Designed in-house and manufactured in the US
- Does not interfere with emissions and 50 state legal
- Factory headers and catalysts retained (no Check Engine Lights)
- Direct bolt-on replacing factory center and side mufflers
- Fits the 2007-2008 997 GT3/GT3RS & 2010 Model GT3s
Dyno Chart
Top to bottom shown are:
-EVOMSit Software with SharkWerks Track Exhaust
-EVOMSit Software only
-Factory stock 2010 GT3
The tuning involves a more aggressive fuel map, timing advance optimization for specific grades of fuel, and a more responsive accelerator pedal.
Summary
With software only, the 2010 GT3 went from 392 RWHP to 404 RWHP at the peak. The car gained about this much horsepower for most of its RPM range.
The car gained over 10 ft-lb of torque at its peak around 6600 RPM and more torque throughout the RPM range.
With the exhaust and software, the gains were higher, bringing it up to 414 RWHP at the peak (22 RWHP net gain), more torque at the peak, and a large gain in torque between 3700 and 5400 RPMs. There is a small drop off in torque below 3400 RPMs which is outside the typical driving range on the track
Here's a video made by our friends at AWD Motorsports in Florida, who did prototype testing of this product as well:
http://www.youtube.com/watch?v=D99V0cS_VaI
If you happen to be from Florida they can demo and install the part for you as well.
Earplugs Not Included
This product is very loud and not wife approved. If you want a more street-friendly exhaust, please consider our bypass exhaust instead.
There is considerable interior noise under acceleration with the Track Exhaust. This is not something we would recommend installing on a street car. It is significantly louder than the factory exhaust or the SharkWerks 997 GT3 Bypass Exhaust System. Please be aware of how loud this system is and try to avoid public roads with traffic. There is a "safe" range for cruising at about 70-75 MPH by keeping the car in 6th gear in the 3000 RPM range that can be used to transport the car to and from a track.
My Opinion
I've driven several hundred miles with GT3 and GT3 RS models using this exhaust system now, and I am pretty excited about what it offers. While it's not something I'd want to commute with
, it has a unique and exotic tone, and is much more tolerable than the straight pipe-options I had heard in the past.
Having been both a passenger and in the car following another running this exhaust, I believe it's not as loud as some of the other traffic on the road. It's louder than almost any cars, but quieter than some motorcycles and V8-domestic muscle cars you may hear. Still, it will put you in the top 1% of loud vehicles on the road and would certainly not be something you could sneak around town in without gathering attention. And this is why we call it a Track Exhaust.

We had one of the first 3.8 GT3's in the country and did extensive testing on our car.
Our testing resulted in some very interesting data and our system was developed a certain way for a reason.
Here are pictures of our World Challenge Sport header system.
More info can be found on our website.
Some of the features of our system are
Equal length runners
F1 3-1 merge collector
SS tubing,CNC machined flanges
200 cell German made sport catalyst OBD 2 compliant.
Direct replacement system that bolts to stock mufflers ( after testing, no power gain has been found replacing stock mufflers) Sport button remains fully functional as do the exhaust flaps.

This is a great solution for those of you who have to live with your car on the road and actually drive it.

I started off wanting a Sharkwerks but my stupid impulsiveness made me end up with a Cargraphics Type 6.... one month later, and shaken to the bones, the car went back to stock.... I have decided to keep it this way... for now..... and dont regret the silence one bit....
i ran the CUP exhaust that has no mufflers and bolt directly to stock cats.
this is the lightest and best cat back exhaust. But not cheap and not quiet at high rpm.
Other companies offer this style system but with slight mufflers to help quiet to raw noise which is a neat feature.
so many options, but it all comes down to your budget.
personally i dont like replacing factory headers and cats, so i keep mine factory, but dont like factory bulky side mufflers thus they get the toss.
any exhaust that eliminates the side mufflers and bolts to stock cats is good in my books. and the perfect combination of lightweight and reasonable price is important along with nice looking tips.
