Has anyone passed the sniffer test with a catted Titek downpipe? Talking about the sniffer test only, not visual.

In fact, post up your experience (whether pass or fail) going through the sniffer test with your Titek downpipe. Would help if you also list your mods.

I'm up for a smog test soon and want to know whether I need to replace the downpipe with the stock one.


TIA!

 

For what it's worth, I have heard many many accounts of the Cobb catted DP passing the sniffer test, and I would imagine that they have similar emissions qualities.

 

That's good info. I have a friend with a Cobb catted dp who would be happy to know this.

Anyone else had experience with the Titek?

 

heard of helix passing

 

sneak in 20% E85 and make sure you're nice and warm, you'll probably pass catless.

Reminds me, I need to get smogged. I put my stock downpipe on 2 weeks ago. I'm 100% E85 right now. Too lazy to stop by somewhere. I am not anticipating issues.

 

I passed with catted Titek. I'll post the numbers if I can find them.

OK found the VIR.

Mods:
Titek up/down
Borla Hush
UTEC running on "stock" setting
Stock airbox in place

Test results: (measured/max allowed)
Idle HC: 97/100 CO%: 0.04/1.0
2500 HC: 24/130 CO%: 0.34/1.0

The tech wasn't interested in looking at anything in particular. Car is obviously modded with a big shiny downpipe, but the dude didn't even blink. HC was pretty close to the limit. Hope that helps.

 

Great stuff! Yeah, the Idle HC looks pretty close. I wonder how I'd do with the GrimmSpeed PnP header and CAI. Looks very clean at 2.5k RPM though. Congrats on passing.

Anyone else?

 

why wouldnt you at least put your stock intake back on, thats like 10 minutes. Your going to get failed on a visual right off the bat

 

For people who have the skill or time to put the stock emission stuff, you should as this keeps the indexes down. ie the op's hc was 97/100 if bar notices that the hc's are always close to the limit they will crack down on the make and model of the car. So if we keep em clean, at least during smogs, then they stay off the Subaru's back. Sorry, I don't mean to rain on your parade.

 

agreed, I mean intakes a no-brainer, and headers/DP are about a 2-3 hour job, and you only have to do it every couple years. its definitely much less hassle than having your car fail a smog check, or worse get your car flagged, then you got yourself a whole other set of problems

 

My AEM intake has the CARB sticker. Before I take it to the test only station, I plan on getting a regular smog check (off the record) and see if the numbers are ok. Would still like to get an idea of things before.

 

Could you explain this a bit more? I'm not sure what you mean by "cracking down on the make and model"? Are you implying that if they see high numbers they will change the max allowed limit, or otherwise change the testing protocol?

And if that is what you mean, do you have some examples of this occurring? I ask becasue it sounds like you have experience with this issue. Thanks.

 

I don't understand why people with AWD worry so much about SMOG?

AWD = No Dyno emission test
No Dyno = NO LOAD on engine
No LOAD = less emission


and intake doesn't ALWAYS mean fail on visual. Visual test depends on the Tech. You can have an open air filter before the MAF. Carb label or Not. doesn't matter.

Any Cat-Back is legal for SMOG, Carb sticker or not...

Test Only Smog and Regular Smog are the same test. 100% identical! If you HAVE to go to a test only center, and your car is 2000+, that mean they(BAR) picked your car ramdomly. Nothing more. Test only centers can SMOG any vehicle that need smog in Cali. If its Test & Repair, they can NOT smog vehicles that require to go to Test Only Center. BUT if its a GOLD Shield Station, they can smog ANY vehicle that needs smog in Cali too... Its confusing at first BUT its really simple...

If you guys are so worry about failing, why not do the Pre-Test FIRST? That way you'll know all the reading and what pass and what doesn't?

Newer Cars nowadays have alot cleaner tailpipe emission, cat or not. You'll be surprise...

Email me for more detail info. I've been doing SMOG/Smog repair for over 6 years and wrenching for over 15 now so... and If you want me to do the pre-test I can do that for you too... and if it pass the pre-test, we'll do the actual test.

Let me know...

I think any help will help the whole. Us 02-04 guys are getting up there in miles, which will still raise flags for you newer folks down the line.

 

I guess I'm doing my part to keep the averages low.

Injen intake (has CARB EO#)
Stock downpipe and catback
deleted TGVs
3mm phenolics
1000cc injectors
Walbro
fuel rail
Mostly Stock ECU (minus re-scaling MAF for intake and injectors for E85, and lowering my idle 100 RPM, because idle was smoother than stock with my 1000cc injectors, I decided to try 100 RPM lower, still smooth and using less fuel idling)
uppipe
E85

Results from the test today:

Idle - 668 RPM
HC = 1ppm (100ppm max to pass)
CO% = 0.00% (1% max to pass)

2540 RPM
HC = 1ppm (130ppm max to pass)
CO% = 0.00% (1% max to pass)

I wonder if this is any better than a stock downpipe 150k mile car on gas instead of E85
