2008 FLHTCU CAT Location?
If I've replaced my stock header with a Rush True Dual system do I still have a Catalytic converter? I've also upgraded the exhaust to Screaming Eagle slip-ons.
Bike is running extremely hot so am trying to figure out exactly what I've got to work with when I call Fuel-Moto to order a tuner.
Thanks.
Shaun

No, the exhaust emission standards for CA are the same as the EPA standards. I don't believe that your model had Cats.
On your right front down tube there is an emission label and if your 08 was originally equipped with cats or thermal reactors it will have OC on the label. If that's there, then you had cats in the mufflers. In any case there were no cats in the header pipes of the pre 09 touring bikes. A Cat won't make your engine run hot.

Dribble, I believe you are somewhat incorrect. California also has the CARB, the Califoria Air Resources Board. The California models have had cats since 2006, except for 2007, located in the mufflers, before the new head pipes were introduced. I have a 2008 parts manual that specifically mentions the Screaming Eagle mufflers as being only 49 state legal, and in ( ) states, not legal in California catalyst equipped models. There is a separate part number for California Screaming Eagle mufflers.
California was always ahead of the rest of the country in smog requirements, even though now the EPA requirements are the same. They still have a carbon canister that the rest of us don't have, as well as the funky gas pump nozzles that supposedly help prevent gas fumes from escaping to the atmosphere when we fuel our vehicles.

When I originally wrote the post I mentioned that sometimes CA comes in a year or two ahead of everyone else. Then I figure it was TMI and deleted it. What CARB will often do is require the pending EPA standards a year or two before the rest of the country. There was a 2006 EPA (Tier 1) emission update.
There is limited information out there regarding which model has what and since the EPA and CARB allow manufacturers to meet their exhaust emission requirements by using an average along the entire model line and even among engine classes, there is no absolute rule that a certain model has to have particular equipment.
I am aware of the additional evaporative emission standard for CA which is controlled with the EVAP canister, but I was referring to exhaust emission standards only, which are (currently) the same for California and the other 49 states. However further research confirms that you are correct and California adopted the EPA 2010 Tier 2 standard beginning with the 2008 model year. Since HD didn't had not done the frame update and had not yet changed the header pipe to incorporate a single cat, the 2008 cats were put in the mufflers. I wasn't sure if they brought them back in 08 or 09 but the bottom line is if the OP changed his mufflers he no longer has CATs.

So this a bit confusing my 08 ultra has Screaming Eagle slip on mufflers. Assuming it is a Ca. bike I am in Ca. How do I know if I have CATs ? Ca. part numbers on the mufflers? Fn! California .

From what I understand, the models that had them before 2009 had them in the mufflers. 2009s didn't have one for some reason, unless it was a Cali model. 2010 and newer has them in the head pipe where the two pipes join together. I verified that mine doesn't have one buy taking the right side muffler off and shining a flashlight in the end of the header pipe. You could do that, its just 2 bolts and a muffler clamp. Thats what I would do. If you take the right side muffler off and you see hallow pipe, then you don't have cat.
