Sniff test is not OBD2.
Not sure where you are located but most states have OBD2 testing.
Additionally trying to find a smog station to "sign off" fraudulently is likely near impossible considering fines can be in the tens of thousands of dollars and could result in legal action against the test station, even including prison time.

 

DSC Sport recommends running a street car w/ DSC at OEM height for maximum benefit. As with the OEM controller, the DSC for 991s has two settings, Normal and Sport.

I can't offer an opinion on your set-up, but call Tom C. at DSC, and he can provide you with a good answer.

 

Hi - when I purchased mine many years ago know - I thought that the car was great out of the box. But even for a lowly .1 TT with such great performance, I expected a little more presence / sound. I bought mine on a whim when I went to my dealership and yes I would have preferred an S but I really liked the color / combo and instant gratification.

So my journey began with mods. I started with Sam and got the Kline headers and exhaust and then Cobb Stage 2 right off the bat (increased power and PDK improvements). Wow - huge difference. Car went from very good to great immediately. Then have done incremental improvements over time. It always fells like you just got something new and its kept it fresh. I really think that the DSC controller is a big bang for the buck. Car is less jittery in normal and handles better in sport. A big difference for daily driving especially on freeways in normal in So Cal. Going to Stage 4 bigger Turbos and other stuff was another big jump up in power. I think for me I may have enough (although they say you never have enough). I haven't done any lowering etc., as its still an ordinary daily that shares duty with my Land Rover and soon to be Cayenne e-Hybrid. I am toying with idea of a 992 TTS but I almost wouldn't mind waiting for the .2. And then deciding between the .2 and the .1 - hybrid vs not. But many (Ferrari and Mac have gone there already). So that may be next move when time permits.

Bottom line - the Porsche platform seems friendly to mods without giving up much (in my case so far - touch wood) reliability. Its been solid and have had no issues. Get in and go as if there were no mods.

 

whos sam btw lots of people mentioning him

 

Sam Ahdoot at ByDesign. He is a RL sponsor but more importantly he is a friend and Porsche specialist for all members. A great person to know even if you never use his services. A wealth of knowledge on our cars.

Always good to work with someone and share ideas before embarking on changing your car and spending $$$’s.

if you just want a car that’s loud that’s easy. If you want one that sounds like it should as a premium high performance car and wring some of the best possible upgrades out of it economically take your time and talk to many who have already taken the steps you are about to. Good luck have fun.

 

THanks man I reached out to him

 

So the car had no CEL so obd2 was fine. That and a sniff test was easy for me to pass. They are supposed to look at engine and exhaust but with our cars you have to take off the fans and possibly bumper so that kinda works in our favor and they don't want to do it. Maybe i got lucky but the first slogged I found didn't check parts. Of course this was with the europipe exhaust. I have moved to decat and other mods but I have the car registered in a smog free county now that is registered in CA.
Sam does have O2 spacers that keep the CEL from tripping but since I went with an XR kit the cel does trip every so often now. With just stage 3 it never did though.

 

You won’t regret it. He is a great guy always willing to help that really knows our cars and how to help us get where we want.
