No, sorry. I only have my own video with an external mic on the rear deck lid and that video from another car. It's loud inside the car under high revs or with lots of throttle, especially with the windows down and when going by walls and guardrails such that the sound reflects back at the car. But on the street, it's possible to be quite unobtrusive by just keeping the revs and throttle down. I find that as an instructor, I can't use my helmet communicator because the helmet mic amplifies the sound into my ears too much. So we just have to talk later!

Sounds really loud. Wondering how it compares to cargraphic loud system. I think Mooty had it at one time. I am in the market. Hard to chose without hearing them though.

I don't know anything about the cargraphic system or how it compares in terms of loudness. But I wouldn't consider buying one without seeing a dyno sheet done by someone independent of their company.

Thx rob. Think Mooty had cargraphic at one time. Maybe he could chime in Two buddies with tracked 6-3's have fabspeed. Like the company but prefer a little higher pitch cup car or 7-3 sound. unfortunately not that many 6-3's showin up at the track to hear other exhausts lately

We recently designed an X-Pipe exhaust for the 996 GT3. It is available catted or catless and uses a center "X" design. Our design utilizes more of a true "X" vs. a "U", as we prefer the sound quality with the true "X" design. This system is also very lightweight at approx. 27 lbs. complete with cats, tips and all hardware. Optional turn-down tips are available.

Below is a picture and video of the system in action...

There is quite a bit of information on Cargraphic in this thread:

just an observation I should make re my new CarGraphic race (light) exhaust - the difference I find after 10-12 sessions now with my 'much' louder system is dramatically less than when I first drove the car. Its amazing how quickly we adapt to the noise difference. At first I thought I'd find it hard to drive without helmet on ... but now quite happy with the windows down and just road driving. Yes the odd old lady falls over ... but then it's also quite windy here.
