Hey guys,

Just a quick question. I am running a Speedtech 70MM exhaust and 100 Octane, will I have any smog issues in SoCal?

Thanks,

 

I recently got a smog on my 996TT turbo and I was told by the smog shop that any mod to the car will need a Carb sticker or it wouldn't pass visual in CA. But most smog shops probably wouldn't know the difference between an aftermarket exhaust or a stock one.

 

Thomas,

I was over at the shop yesterday setting an appointment with Betim and forgot to ask that question. Do you think the 100 Octane will be an issue?

Have we met?

Thanks,

 

Depends where you go. If it sounds loud, between the exhaust and the LWFW- and they smell the race gas- they might look real hard. From a tailpipe point of view I would think you should be fine.

 

Any suggestions on where to go?

 

i would go to a dealership they just wanna get your car out there and don't know whats what (a non porsche dearlership) be sure you tellem u have all wheel dr they don't know that eather and the test is way easier. any way when i had mine done

 

I passed the smog test in socal with flying colors with your same exhaust, giac ecu, on pump gas. You shouldn't have any problems passing the visual, as they are typically not very familiar with our cars. we also have an advantage since our cars are all wheel drive, so they can't put them on the rollers. If possible, i would switch back to 91 oct, although you'll probably do fine 100.

 

100 cel cats, GIAC, miltek exhaust etc.
The local smog guy just looked at the engine and said every seems fine then ran the regular tests - passed with flying colors.

 

Take it to the cheesiest smog place you can find where you know they've never seen a Porsche. I passed with flying colors.

 

Just exhaust u should be fine...but I don't know why you put 100 oct in there

 

The car won't pass the visual inspection but should pass the actual test no problem. If the guy is a jerk, he is going to put in the system that you have tampered with the smog equipment. That's what happened to me.

I would tell the technician that you have an aftermarket exhaust with a catalyst BEFORE actually signing up. Tell them you are not expecting any favors but don't want to even begin if they're going to fail you. At least you'll know if he's a jerk before he writes you up.

 

Sorry but that sounds like a bad plan. Smog shops are regularly tested by undercovers. If a shop has a stranger come in and say, essentially, 'legally you should fail me', who would go forward?

Finding the shop 'least likely for a Porsche dealer to choose' is a plan...

 

Like I posted in another thread (and here) - simply take it to a regular smog shop which is unlikely to recognize an after market exhaust system.

I always use the one next to the ez-lube place in our area.

The owner / tech was more interested in the TT for what it was as he doesn't get many to smog and makes a change from the run of the mill.

 

thanks guys, I will drop the 100 down to 91, which suck btw, and fine a place. I was going to take it to AAA by my house, but that may be a bad choice.

I use the 100 because 91 blows. The 100 makes it run nice + with the exhaust I am seeing 1.0 bar.

 

BTW, with the stock flash you can run 50-50% with 91 and 100 octane and get the same results. The stock program can only 'use' so much of the octane- basically around 95 octane.
