Hi Alex,
This may be just what I have been awaiting. Will this setup pass California Emissions testing?
Duane Menefee
It's hard to predict what will or won't "pass California Emissions testing" at a given smog station on a given day. However, the package is not legal in California, or anywhere else in the US, for street use. The reason is that the Cargraphics catback eliminates the 2 catalysts that are installed in the Cayman's silencer (muffler). EPA regulations prohibit this, nationwide.

Emissions-wise I'm confident that we're ok on this one, already done, tested (pre-tested I should say) but absolutely... changing out an air-intake, plenum etc... none of that is "technically" legal in California. But they never open the engine cover and dig around so...
The Cargraphic muffler is the one used for this kit but Todd has tuned for other exhausts and will continue to do so. We certainly don't want people being "forced" into buying an Exhaust if they already have one that they're happy with. Same sort of thing on the TT side (although the effects there are a lot wider). The reason the Cargraphic was chosen was that it's super-quiet and doesn't resonate as much as most of the exhausts out there. Resonance inside the Cayman is obviously a touchy subject so we want to be sure we start with a recommendation that's as quiet as can be and then go from there.
Unfortunately there is no after-market company that builds kits for Porsche that has a SMOG "cert" unlike in the Corvette, Mustang world... Not RuF, not Gemballa, TechArt, Softronic, EVO etc....
Plenum
The plenum is the piece that goes between the Cayman throttle body and the intake runners. The factory piece is a long black plastic tube with a divider down the middle. There are aftermarket replacements which are designed to allow the air to flow easier/faster into the engine and increase horsepower and torque.
Softronic
SOFTRONIC produces DME programming and hardware to suit your companies specifications. Our current software suite is a complex matched set of programs housed in a Flash Manager and Flash Client. This software is matched with two cables, an End User and Master Cable. The SOFTRONIC proprietary flashing solution outperforms all other combinations in speed and accuracy including the factory Porsche equipment.

The difference is amazing! The car was fun before but now it is incredible! I am still planning on installing the IPD race plenum and GT3 throttle body as soon as I get it and I will dyno the car then. But so far it feels like a huge HP gain!

The first stage of the mods was:
- Borla catback exhaust
- IPD Plenum
- Evom V-flow
- De-snork
Drove the car for a week and definitely felt a nice improvement but now with the Under-drive Pulley and the EVOMSit Software it is a different car, it really gets the full potential from the other performance mods. The Software is actually tuned for the race Plenum which I will install as soon as RSS sends it to me! I am really happy with the way the car feels and sounds! It does feel like a beast!
Great work! thanks to Evolution, Shark Werks and RSS!

I went by EVO on Friday and someone was driving off right as I turned down the street! Sounded good though.
Try to get by before it departs.
Douge,
You are always welcome to swing by and check it out! If you have a particular time that works for you let me know and I will make sure it is here and waiting for your arrival! It is also fun to come check out the Gumperts as well!!
