Cargraphics valved exhaust going in today.
*Headers
*100 cell cats (to help heat for 3.5 season drives)
*Pressureless closed valves
*Switch for opening and closing valves will go in place of sunroof switch.
*Exhaust tips need to be cerakoted.
Was there for initial startup ... sounded louder closed than I thought but I also was concerned that they would be too quiet.
I'll update impressions of sound after driving it for a while.
Overall build quality looks very good.
Exhaust sounds excellent! Near stock sound level when closed and deep and throaty when open. At WOT glorious.
Stainless has colored up nicely after being exposed to heat.
Old sunroof switch location used for electronic valve switch ... valves stay at position of switch even after shutting car down and staring it back up. I didn't expect that but that is the way to have it work..
Tim Olsen is posting sound files on his site.
The exhaust looks great, ill check out Olsen to catch a sound bite. I apologize if I missed this but did you retain heat? I assume so given your location.

Yes ... retained the heat with 100 cell cats. Cats do help the heating system generate heat in this design. It's like having a clump of coal in the heater box.
Olsen Motorsports video of Cargraphics exhaust.
Keep in mind that it's filmed indoors with decibel meter at the tailpipe and not trackside.
I am very happy with it and look forward to really testing it out on road trips when the weather gets better.
Heater with 100 cell cats works significantly better than open heater boxes and no cats.
