My Audition of Cargraphic Exhaust
I was MOST impressed with the quality of construction of the Cargraphic. From my admittedly amateurish observation--i.e. based on look and feel and knocking on the thing

BTW, the Cargraphic exhaust has a heat shield, like stock. The other side of the exhaust is the engine (some belt?), so I think it's good to have a heat shield. How protective/effective this is? I don't know but I would assume from the reputation of the company the engineers knew what they were doing.
Ed's neighborhood's dogs are safe. At idle and not under load, the Cargraphic Loud is NOT loud at all. It does bubble, at a frequency that is lower than stock but not as deep as AWE. I would say if stock bubbling sounds like striking two thin platic/wooden sticks together: wimpy and mute, then Cargraphic is more machine gun like (at least in movies; although I am from VN originally I fortunately have never heard machine gun live), a little deeper than stock, not harsh or raspy. And AWE sounds like a wet bubbling with the deepest sound yet.
I've been told that droning is reduced if you have a cross pipe between the 2 cans in the back. The stock Porsche exhaust has this cross pipe. I forgot to look when I was at Stuttgart Performance and now don't have a picture. Does anyone know if Cargraphic has a cross pipe?
I am sure I will have more to add once I get a ride in Ed's car a couple weekends from now (trying to listen to Anthony's too). But so far, I like it! I *think* I have a slight preference for the sound of AWE still (strictly personal preference), but Cargraphic is close enough to AWE that I could see myself getting one, easily.
AAAHT (Anthony), you got PM. Thanks.
