DEQ inpesction with catless DPs?

[mwlmd]

This question is for those of you with catless DPs. Apart from the CEL, how do you pass emmisions testing with no cats?

I assume most areas require once a year testing. Is there an electronic fix or do you install OEM DPs for emission test?

I would think it would be quite obvious to the DEQ test folks that a "new" car smells like it has no cats.

I know there are catted DPs. I am just curious what the catless folks do...

Here in Texas you can take your car to a county where there is no requirement for emissions check and they give you a sticker but you have to promise to get it inspected in your home county I think.

They read the ODB here in Texas so if you have an emission error it will be there unless you have a device for clearing it.

I opted for high flow dps with 400 cell cats it's expensive but they were worth 21hp and more sound. My SA told me he has a guy with an M3 that pays round trip to put on stock for inspection and then take them off.

NVM...just saw the signature

in CA only cars past 5 years old need to get tested -- and you can always pay one of the testing shops off.

in FL there is no emissions testing.

The super duper expensive Noelle High Flow Down Pipes. They add 21hp according to the Noelle website. They are Boysen and have the BMW imprint on them.

Those are $3000 with the cats, I considered them first. They cannot guarantee that there won't be CEL but there are users who have them and have not had a CEL. I bought the Noelle because its' certain there won't be a CEL and they are OEM.

Pretty well now that it has all had time to mesh together. I am looking forward to a little cooler weather for getting in some good quarter mile runs. I have some data posted on other threads from Vbox runs. I am happy with how the car is set up now. It sounds really good and runs as well as it sounds.

I'm thinking this is the likely option I will go with.
