Hello.
I have a 2004 2500 std cab california engine my question is which exaust would i order one for an 04 or one for an 04.5? Since mine does have a cat.
Also i installed a CB in my truck an i was wondering how you guys ran the antenna wire into the cab i have it mounted on the 4x4 shifter plastic bezel
thanks dennis

 

To determine if you have an 04 or 04.5, look on the driver side door where the information tag is, if it was built after 1 jan 04, it's an 04.5. The fact that you have a cat tells me that you have an 04.5, but I don't know about CA vehicles. See if the pipe is 4" or 3.5...

Where is your antenna at on the truck? There are plastic gromets under the steering wheel that you can cut and push the wire out, and I think that there are some on the back/under the cab somewhere...

Here's where I run my stuff out to the engine compartment...

 

thanks the antenna's are on the tool box behind the cab. I know my truck is an 04 b/c its mechanical wastegate
thanks again ill look for the rubber gromets under the truck

 

Yeah... that's another one of the give a ways...

Worse case is that you could drill a hole and get a grommet...
