Hello to everyone, Sorry for the long post. I just completed installation of AWE's 997 GT3 exhaust on BrianBento's 997 GT3. For starters I have installed every exhaust system imaginable on Pcars form early 911 to current models. This is by far the best fitting system I have had the pleasure to install on a Pcar. The Build quality is excellent, the welds are beautifull , all the welds in the ports (flanges) and on the collectors are port matched. The fit is perfect, no interferance anywhere. It went on perfectly, there was no prying, modifying needed at all (Most all exhaust systems need a little). They also use top quality hardware throughout, even the hanger brackets for the cats use factory style bushings with factory quality materials. The retaining straps for the mufflers are of equal quality, matter of fact they are polished Porsche parts. The mufflers have small angled wedges welded to the back of them that allow the muffler to sit flush against the hanger brackets. Great attention to detail in the entire build. Lets put it this way if the factory were to offer an exhaust of this style it would look just like this! It sounds awesome as well, at idle it is fairly subdued, its about as loud as the stock exhaust in sport mode at idle, crack the throttle and it screams like a banshee!!! I am sure brianbento will give a driving review soon. I highly recommend this exhaust system to all. Mike at AWE has been great to deal with, he got all the parts to us in a flash.

Great product Awe,
Gabe.

I can say I had the same impressions with their 997TT exhaust. I also did the install myself at it was without a hitch - all parts fits perfectly without any tweaking. Construction is top notch with no shortcuts. Mike at AWE is an excellent resource for us - a no BS kind of guy. AWE also has been consistently a straight-shooting company whose dedication to bring out quality products is apparent in their work.

you actually had your hearing aids turned on?

OldGuy

Were lucky to have such good exhaust sponsors such as Todd, the sharster and others.
Congrats to you for your AWE install.

it sounded awsome!!!!!!!! best sounding exhaust .... well maybe next to my new gmg gt exhaust for the gt2

Does AWE have any posted dB readings as ALL our local tracks except Mosport, have very strictly enforced noise levels.
For example 997 GT3's and RS's have been sent packing using the stock exhaust in "Sport" mode

LOL, even in quiet mode, RS or 7GT3 cannot pass laguna seca sound check.

Mooty, I'm looking forward to taking my GT3 to Laguna Seca, what do I need to do to pass the sound test?

mooty

short shift after T5, move track left, and 1/2 throttle.

Carrera GT

Turning off Sport will help, but what's the point in laps punctuated by a slow grind up the first part of the hill?
I put on two 3" dryer vent elbows -- pointed 90 degree to the driver side (away from the test mic) and found it made no significant difference to angle the elbows up or down. I used some hi temp rubber to protect the black exhaust tips and conventional hose clamps -- just cut the vent to allow it to flare out and around the tips.
In this way, you can run in Sport mode wide open from the apex and drive a line that takes advantage of the camber near the middle of the track instead of hiding away on the left.

Todd/A.W.E.

Unfortunately, sound volume level recording appears to be relative to the specific environment where the testing is being conducted.

For example, SCCA sound limits (which are regularly adopted by most tracks and sanctioning bodies) prescribe a 104 dbA actionable limit as measured 50 feet from edge of track at a height of 3-6 ft.

Before we did exhaust development on the GT3, we knew that people were getting into trouble even with the stock exhausts sound volumes. We did some limit testing of our own, with the same SCCA specs as above, and WOT 3rd gear in the GT3 only registered 84 dbA where we tested. This suggested to us that such things as trees, hills, and track banking can substantially affect sound volumes, and unless we can test at each specific monitoring station of every regulated track, we could not make any blanket statements regarding sound limits and our exhaust.

Instead, we took another clue from Porsche Motorsports, and offer turn down tips like they do on the RSR and endurance cup car exhausts. These tips can be installed in a matter of minutes, and should reduce volume enough to make the stewards happy. "Should" being the operative word.
