Is it possible to pass emissions with a 100 cell cat exhaust? I really don't want to settle for a wimpy exhaust note

 

Yes, our exhausts with 100 cell cats pass all the time...

 

I'm also interested in this. Registered in DE where they don't do emissions, but moving back to NJ soon and have Miltek w/ 100 cells. Have my stock exhaust though so if all else fails I can swap back to that temporarily.

 

Is it usual that any 100 cell cats will pass emissions or can you only testify for yours?

 

HI,I passed with my 100 cell Milltek..

 

Awesome. Thanks for the info. One less thing to worry about when moving back to NJ. Now to get those mags pinned for my archangel to 15rds. Gay NJ laws.

 

Past the sniff test with flying colors with my new Speedtech 3.0 with 100cel. Unfortunately I have two "readiness codes" that are not clearing Catalyst Monitoring and Oxygen Sensor Heater Monitoring.

Not sure if this is a function of not enough miles or my flash??

 

Hi,Didnt you also pass with your Milltek...

 

I can only speak to ours. I do not know how others perform in terms of passing emmissions testing parameters.

 

Do some states still use exhaust gas analysis? I have seen cars that pass using this technique, but would fail if an OBD scan were performed because more than 1 readiness code was thrown.

 

Your 100 cell exhaust though sets off lights though, correct? What can we do to fix that

 

No, it does not set off the CEL. We have sold hundreds of systems without a CEL issue.

 

Confirmed here.

 

Confirmed as well. Just air cared my car with a 100 cell speed tech xflow with no issues. I also have an epl stage 2 flash which puts my o2's in a readiness situation so I could run catless if I wanted.
They never sniff tested my car they have always just plugged in the computer and it comes back as all sensors are in the ready position with no error codes. All good
Got to say still loving my speedtech xflow, with the windows down the turbo whistle is freakin awesome. Good work John.

 

the best thing to do is a to compliment a tune with the exhaust and worries are over
100 cell cats do go bad eventually...
